------------------------------------------------------------------- Wed Aug 14 19:09:12 UTC 2024 - Arjen de Korte <suse+build@de-korte.org> - update to 2.3.21.1 and pigeonhole 0.5.21.1 Dovecot 2.3.21.1 - CVE-2024-23184: A large number of address headers in email resulted in excessive CPU usage. [boo#1229184] - CVE-2024-23185: Abnormally large email headers are now truncated or discarded, with a limit of 10MB on a single header and 50MB for all the headers of all the parts of an email. [boo#1229183] - oauth2: Dovecot would send client_id and client_secret as POST parameters to introspection server. These need to be optionally in Basic auth instead as required by OIDC specification. - oauth2: JWT key type check was too strict. - oauth2: JWT token audience was not validated against client_id as required by OIDC specification. - oauth2: XOAUTH2 and OAUTHBEARER mechanisms were not giving out protocol specific error message on all errors. This broke OIDC discovery. - oauth2: JWT aud validation was not performed if aud was missing from token, but was configured on Dovecot. ------------------------------------------------------------------- Mon Nov 6 15:58:22 UTC 2023 - Dominique Leuenberger <dimstar@opensuse.org> - Fix build with RPM 4.19: unnumbered patches are no longer supported. ------------------------------------------------------------------- Fri Sep 15 12:12:44 UTC 2023 - Arjen de Korte <suse+build@de-korte.org> - update to 2.3.21 and pigeonhole 0.5.21 Dovecot 2.3.21 * lib-oauth2: Allow JWT tokens to be validated with missing typ field. The typ field is left out by some key issuers to conserve space, notably kubernetes. Now missing typ is tolerated, but if present, it still must be "jwt". + auth: Auth passdb and userdb reply can contain "event_<name>=value" which will be added to login event and mail user event respectively. + lib-master: Set process title during various initialization stages to clearly describe what the process is waiting on. + lib-storage: The mail_temp_scan_interval is now fuzzed incrementing it by 0..30% based on username's hash to reduce the chance of load spikes. + lib-storage: The temp file scan has been moved from the open of the mailbox to the close, to reduce the latency perceived by users. + stats: If metric has fields specified, all these fields are exported as counters to prometheus exposition. See https://doc.dovecot.org/configuration_manual/stats/openmetrics/. - *-login: Processes might have crashed when a SSL connection disconnects uncleanly. - acl: When plugin was loaded \HasChildren and \HasNoChildren flags were calculated incorrectly for mailboxes containing '*' and '%' in their names. - auth: Crash occured if a connection to PostgreSQL database server failed during startup. - auth: Logins with invalid passwords (e.g. unknown scheme) in passdb were failing with "password mismatch" instead of "internal error". - auth: XOAUTH2 and OAUTHBEARER mechanisms were not giving out protocol specific error message on all errors. This especially broke OIDC discovery. - dbox: When last_temp_file_scan header wasn't set (especially after dsync migration), the next mailbox open always triggers the temp file scan. This could have caused a load spike after migrations. Fixed by using the mailbox directory's atime when the header isn't set, which usually moves the scan time into the future. - dict-redis: A crash would occur on transaction rollback. - dsync: Infinite loop causing out of memory would occur when handling mailbox deletion from remote end and hierarchy separators would differ. - dsync: Incremental dsync failed for folder names ending with '%', unless BROKENCHAR was set. Also folder names with '%' elsewhere in them caused each incremental dsync to unnecessarily rename the folder to a temporary name and back. v2.3.19 regression. - imap-hibernate: If an IMAP client unhibernation timed out with "(version received)", the unhibernation could still have successfully finished later on and continued working normally. This was rather confusing, because imap-hibernate already logged that the client got disconnected. Avoid this by forcing the connection to shutdown on unhibernation timeout. - imapc: Crashed when a folder mapped through the virtual plugin disappears from the storage. - imapc: EXPUNGE, EXISTS or FETCH replies from a server for a previously selected mailbox could have been processed as if they belonged to the new mailbox currently being selected. This could have caused warnings. - lib-http: Dovecot HTTP server (doveadm, stats/openmetrics) may have disconnected HTTP clients before the response is fully sent. This happened only on busy servers where kernel's socket buffers were rather full. - lib-http: Fixed a potential crash on http-server if a client disconnected early. v2.3.18 regression. - lib-index: Index file corruption could have caused a crash. Fixes: Panic: file mail-transaction-log-view.c: line 165 (mail_transaction_log_view_set): assertion failed: (min_file_seq <= max_file_seq). - lib-index: Purging an existing >1GB cache file can crash. Now cache files still above 1GB after purging are removed. Fixes: Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset): assertion failed: (offset < 0x40000000) - lib-lua: A HTTP client could not resolve DNS names in mail processes, because it expected "the dns-client" socket to exist in the current directory. - lib-oauth2: Dovecot would send client_id and client_secret as POST parameters to the introspection server. These need to be optionally in Basic auth instead. - lib-oauth2: JWT aud validation was not performed if aud was missing from a token, but was configured on Dovecot. - lib-oauth2: JWT key type check was too strict. - lib-oauth2: JWT token audience was not validated against client_id as required by the specification. - lib-ssl-iostream: Using the ssl_require_crl=yes setting may have caused CRL check failures for outgoing SSL/TLS connections, although it was supposed to affect checking CRLs only for client-side SSL certificates. v2.3.17 regression. - lib-sql: MySQL driver leaked memory when connection failed. - lib-storage: Various fixes when running into out of disk space. - master: Service idle_kill setting didn't work properly on busy servers. It was very unlikely that any process was idling long enough to become killed. Also the idle_kill handling code was using quite a lot of CPU on the master process when there were a lot of processes (e.g. imap). The new behavior is to track the lowest number of idling processes every idle_kill time interval and then kill that many idling processes. - mdbox: Temp file scan was done for always empty directories. - mdbox: The fdatasync() call was done in wrong parent directory when writing mails. Also on a failure it crashed instead of logging an error. - notify_status: The plugin crashes if any user initialization fails. - pop3: Sending command with the ':' character caused an assert-crash. v2.3.18 regression. Fixes: Panic: event_reason_code_prefix(): name has ':' - stats: Fix panic when a nonexistent event exporter was referenced while adding a new metric dynamically via doveadm stats add. This produces a proper error now. - stats: If process exported a lot of events and then exited, some of the last events may have become lost. - stats: Invalid Prometheus label names were created with specific histogram group_by configurations. Prometheus rejected these labels. - welcome: The plugin didn't execute in some situations that created INBOX but didn't open it, e.g. if GETMETADATA was used before the INBOX was opened. Pigeonhole v0.5.21 - sieve: Using the deleteheader action on a message with a broken/invalid header can cause the Sieve interpreter to crash with an assert panic. This can happen e.g. when the message is missing the empty EOH line between the headers and the body of the message. Fixes: Panic: file edit-mail.c: line 820 (edit_mail_headers_parse): assertion failed: (body_offset > 0). - sieve: Pigeonhole added an extra Message-ID header during mail forwarding when the existing one was invalid. Now it adds the Message-ID only if it is entirely missing. Existing Message-ID(s) are left unchanged. ------------------------------------------------------------------- Mon Mar 27 09:15:10 UTC 2023 - Martin Liška <mliska@suse.cz> - Add upstream fix-strict-aliasing.patch that addresses violation of strict aliasing. ------------------------------------------------------------------- Thu Mar 23 14:45:26 UTC 2023 - Martin Liška <mliska@suse.cz> - Enable LTO now as it works now (boo#1156301). ------------------------------------------------------------------- Sun Feb 5 16:07:02 UTC 2023 - Arjen de Korte <suse+build@de-korte.org> - Add patch to fix building with OpenSSL-3 (boo#1207958) + fix-build-with-openssl-3.patch ------------------------------------------------------------------- Thu Dec 22 20:47:52 UTC 2022 - Michael Ströder <michael@stroeder.com> - removed obsolete dovecot-2.3.19-fix-doveadm-sync-special-folders.patch - update to 2.3.20 and pigeonhole 0.5.20 + Add dsync_features=no-header-hashes. When this setting is enabled and one dsync side doesn't support mail GUIDs (i.e. imapc), there is no fallback to using header hashes. Instead, dsync assumes that all mails with identical IMAP UIDs contains the same mail contents. This can significantly improve dsync performance with some IMAP servers that don't support caching Date/Message-ID headers. + lua: HTTP client has more settings now, see https://doc.dovecot.org/admin_manual/lua/#dovecot.http.client + replicator: "doveadm replicator status" command now outputs when the next sync is expected for the user. - LAYOUT=index: duplicate GUIDs were not cleaned out. Also the list recovery was not optimal. - auth: Assert crash would occur when iterating multiple userdb backends. - director: Logging into director using master user with auth_master_user_separator character redirected user to a wrong backend, unless master_user_separator setting was also set to the same value. Merged these into auth_master_user_separator. - dsync: Couldn't always fix folder GUID conflicts automatically with Maildir format. This resulted in replication repeatedly failing with "Remote lost mailbox GUID". - dsync: Failed to migrate INBOX when using namespace prefix=INBOX/, resulting in "Remote lost mailbox GUID" errors. - dsync: INBOX was created too early with namespace prefix=INBOX/, resulting a GUID conflict. This may have been resolved automatically, but not always. - dsync: v2.3.18 regression: Wrong imapc password with dsync caused Panic: file lib-event.c: line 506 (event_pop_global): assertion failed: (event == current_global_event) - imapc: Requesting STATUS for a mailbox with imapc and INDEXPVT configured did not return correct (private) unseen counts. - lib-dict: Process would crash when committing data to redis without dict proxy. - lib-mail: Corrupted cached BODYSTRUCTURE caused panic during FETCH. Fixes: Panic: file message-part-data.c: line 579 (message_part_is_attachment): assertion failed: (data != NULL). v2.3.13 regression. - lib-storage: mail_attribute_dict with dict-sql failed when it tried to lookup empty dict keys. - lib: ioloop-kqueue was missing include breaking some BSD builds. - lua-http: Dovecot Lua HTTP client could not resolve DNS names in mail processes, because it expected "dns-client" socket to exist in the current directory. - oauth2: Using %{oauth2:name} variables could cause useless introspections. - pop3: Sending POP3 command with ':' character caused an assert-crash. v2.3.18 regression. - replicator: Replication queue had various issues, potentially causing replication requests to become stuck. - stats: Invalid Prometheus label names were created with specific histogram group_by configurations. Prometheus rejected these labels. ------------------------------------------------------------------- Tue Dec 20 22:30:25 UTC 2022 - Thiago Macieira <thiago@kde.org> - Add suppor for Zstandard (zstd) to the compression (zlib) plugin: zstd has a better compression ratio than gzip for the same amount of CPU work, or takes less CPU to compress the same. It's also faster to decompress. - Add dovecot-2.3.19-fix-doveadm-sync-special-folders.patch: Patches from the release-2.3 branch that fix issues importing the INBOX folder from a Cyrus IMAP server and dealing with auto-creating folders that haven't yet been created ------------------------------------------------------------------- Tue Jun 14 14:17:29 UTC 2022 - Michael Ströder <michael@stroeder.com> - update to 2.3.19.1 * doveadm deduplicate: Non-duplicate mails were deleted. v2.3.19 regression. * auth: Crash would occur when iterating multiple backends. Fixes: Panic: file userdb-blocking.c: line 125 (userdb_blocking_iter_next): assertion failed: (ctx->conn != NULL) ------------------------------------------------------------------- Tue May 10 17:55:17 UTC 2022 - Arjen de Korte <suse+build@de-korte.org> - update to 2.3.19 and pigeonhole 0.5.19 Dovecot 2.3.19 + Added mail_user_session_finished event, which is emitted when the mail user session is finished (e.g. imap, pop3, lmtp). It also includes fields with some process statistics information. See https://doc.dovecot.org/admin_manual/list_of_events/ for more information. + Added process_shutdown_filter setting. When an event matches the filter, the process will be shutdown after the current connection(s) have finished. This is intended to reduce memory usage of long-running imap processes that keep a lot of memory allocated instead of freeing it to the OS. + auth: Add cache hit indicator to auth passdb/userdb finished events. See https://doc.dovecot.org/admin_manual/list_of_events/ for more information. + doveadm deduplicate: Performance is improved significantly. + imapc: COPY commands were sent one mail at a time to the remote IMAP server. Now the copying is buffered, so multiple mails can be copied with a single COPY command. + lib-lua: Add a Lua interface to Dovecot's HTTP client library. See https://doc.dovecot.org/admin_manual/lua/ for more information. - auth: Cache lookup would use incorrect cache key after username change. - auth: Improve handling unexpected LDAP connection errors/hangs. Try to fix up these cases by reconnecting to the LDAP server and aborting LDAP requests earlier. - auth: Process crashed if userdb iteration was attempted while auth-workers were already full handling auth requests. - auth: db-oauth2: Using %{oauth2:name} variables caused unnecessary introspection requests. - dict: Timeouts may have been leaked at deinit. - director: Ring may have become unstable if a backend's tag was changed. It could also have caused director process to crash. - doveadm kick: Numeric parameter was treated as IP address. - doveadm: Proxying can panic when flushing print output. Fixes Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed: (ioloop == current_ioloop). - doveadm sync: BROKENCHAR was wrongly changed to '_' character when migrating mailboxes. This was set by default to %, so any mailbox names containing % characters were modified to "_25". - imapc: Copying or moving mails with doveadm to an imapc mailbox could have produced "Error: Syncing mailbox '[...]' failed" Errors. The operation itself succeeded but attempting to sync the destination mailbox failed. - imapc: Prevent index log synchronization errors when two or more imapc sessions are adding messages to the same mailbox index files, i.e. INDEX=MEMORY is not used. - indexer: Process was slowly leaking memory for each indexing request. - lib-fts: fts header filters caused binary content to be sent to the indexer with non-default configuration. - doveadm-server: Process could hang in some situations when printing output to TCP client, e.g. when printing doveadm sync state. - lib-index: dovecot.index.log files were often read and parsed entirely, rather than only the parts that were actually necessary. This mainly increased CPU usage. - lmtp-proxy: Session ID forwarding would cause same session IDs being used when delivering same mail to multiple backends. - log: Log prefix update may have been lost if log process was busy. This could have caused log prefixes to be empty or in some cases reused between sessions, i.e. log lines could have been logged for the wrong user/session. - mail_crypt: Plugin crashes if it's loaded only for some users. Fixes Panic: Module context mail_crypt_user_module missing. - mail_crypt: When LMTP was delivering mails to both recipients with mail encryption enabled and not enabled, the non-encrypted recipients may have gotten mails encrypted anyway. This happened when the first recipient was encrypted (mail_crypt_save_version=2) and the 2nd recipient was not encrypted (mail_crypt_save_version=0). - pop3: Session would crash if empty line was sent. - stats: HTTP server leaked memory. - submission-login: Long credentials, such as OAUTH2 tokens, were refused during SASL interactive due to submission server applying line length limits. - submission-login: When proxying to remote host, authentication was not using interactive SASL when logging in using long credentials such as OAUTH2 tokens. This caused authentication to fail due to line length constraints in SMTP protocol. - submission: Terminating the client connection with QUIT command after mail transaction is started with MAIL command and before it is finished with DATA/BDAT can cause a segfault crash. - virtual: doveadm search queries with mailbox-guid as the only parameter crashes: Panic: file virtual-search.c: line 77 (virtual_search_get_records): assertion failed: (result != 0) Pigeonhole v0.5.19 * This release is done to maintain parity with dovecot 2.3.19 release, so it does not contain any news-worthy changes. ------------------------------------------------------------------- Thu Feb 3 20:51:46 UTC 2022 - Michael Ströder <michael@stroeder.com> - update to 2.3.18 and pigeonhole to 0.5.18 * removed obsolete mail-cache-bigendian.diff Dovecot 2.3.18 * Removed mail_cache_lookup_finished event. This event wasn't especially useful, but it increased CPU usage significantly. * fts: Don't index inline base64 encoded content in FTS indexes using the generic tokenizer. This reduces the FTS index sizes by removing input that is very unlikely to be searched for. See https://doc.dovecot.org/configuration_manual/fts/tokenization for details on how base64 is detected. Only applies when using libfts. * lmtp: Session IDs are now preserved through proxied connections, so LMTP sessions can be tracked. This slightly changes the LMTP session ID format by appending ":Tn" (transaction), ":Pn" (proxy connection) and ":Rn" (recipient) counters after the session ID prefix. + Events now have "reason_code" field, which can provide a list of reasons why the event is happening. See https://doc.dovecot.org/admin_manual/event_reasons/ + New events are added. See https://doc.dovecot.org/admin_manual/list_of_events/ + fts: Added fts_header_excludes and fts_header_includes settings to specify which headers to index. See https://doc.dovecot.org/settings/plugin/fts-plugin#plugin-fts-setting-fts-header-excludes for configuration details. + fts: Initialize the textcat language detection library only once per process. This can reduce CPU usage if fts_languages setting has multiple languages listed and service indexer-worker { service_count } isn't 1. Only applies when using libfts. + lib-storage: Reduced CPU usage significantly for some operations that accessed lots of emails (e.g. fetching all flags in a folder, SORT, ...) + lib: DOVECOT_PREREQ() - Add micro version which enables compiling external plugins against different versions of Dovecot. + lmtp: Added new lmtp_verbose_replies setting that makes errors sent to the LMTP client much more verbose with details about why exactly backend proxy connections or commands are failing. + submission: Support implicit SASL EXTERNAL with submission_client_workarounds=implicit-auth-external. This allows automatically logging in when SSL client certificate is present. - *-login: Statistics were disabled if stats process connection was lost. - auth: Authentication master user login fails with SCRAM-* SASL mechanisms. - auth: With auth_cache_verify_password_with_worker=yes, passdb extra fields in the auth cache got lost. - doveadm: Fixed crash if zlib_save_level setting was specified, but zlib_save was unset. v2.3.15 regression. - doveadm: Proxying can panic when flushing print output. v2.3.17 regression. Fixes: Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed: (ioloop == current_ioloop) - doveadm: stats add --group-by parameter didn't work. - fts: Using email-address fts tokenizer could result in excessive memory usage with garbage email input. This could cause the indexer-worker processes to fail due to reaching the VSZ memory size limit. Only applies when using libfts. - imap: A SEARCH command timing out while fts returns indexes may timeout returning "NO [SERVERBUG]", while it should return "NO [INUSE]" instead. - imap: LIST-EXTENDED doesn't return STATUS for all folders. Sending LIST .. RETURN (SUBSCRIBED STATUS (...)) did not return STATUS for folders that are not subscribed when they have a child folder that is subscribed as mandated by IMAP RFCs. - imapc: Mailbox vsize calculation crashed with Panic: file index-mailbox-size.c: line 344 (index_mailbox_vsize_hdr_add_missing): assertion failed: (mails_left > 0) - indexer: If indexer-worker crashes, the request it was processing gets stuck in the indexer process. This stops indexing for the folder until indexer process is restarted. v2.3.14 regression. - indexer: Process was slowly leaking memory for each indexing request. - lib-event: Unnamed events were wrongly filtered out for event/metric filters like "event=abc OR something_independent_of_event_name". - lib-index: 64-bit big endian CPUs handle last_used field in dovecot.index.cache wrong. - lib-ssl-iostream: Fix buggy OpenSSL error handling without assert-crashing. If there is no error available, log it as an error instead of crashing. The previous fix for this in v2.3.11 was incomplete. Fixes Panic: file istream-openssl.c: line 51 (i_stream_ssl_read_real): assertion failed: (errno != 0) - lmtp: Out-of-memory issues can happen when proxying large messages to LMTP backend servers that accept the message data too slow. - master: HAProxy header parsing has read buffer overflow if provided header size is invalid. This happens only if inet_listener { haproxy=yes } is configured and only if the remote IP address is in haproxy_trusted_networks. - old_stats: Plugin kept increasing memory usage, which became noticeable with long-running imap sessions. - stats: Dynamically adding same metric multiple times causes multiple stats. - submission-login: Authentication does not accept OAUTH2 token (or other very long credentials) because it considers the line to be too long. - submission-login: Process can crash if HELO is pipelined with an invalid domain. - submission-proxy: Don't use SASL-IR if it would make the AUTH command line longer than 512 bytes. - submission: Service would crash if relay server authentication failed. - virtual: FTS search in a virtual folder could crash if there are duplicate mailbox GUIDs. This mainly happened when user had both INBOX and INBOX/INBOX folders and the namespace prefix was INBOX/. Fixes Panic: file hash.c: line 252 (hash_table_insert_node): assertion failed: (opcode == HASH_TABLE_OP_UPDATE) - virtual: If mailbox opening fails, the backend mailbox is leaked and process crashes when client disconnects. Fixes Panic: file mail-user.c: line 232 (mail_user_deinit): assertion failed: ((*user)->refcount == 1) - virtual: Searching headers in virtual folders didn't always use full-text search indexes, if fts_enforced=no or body. Pigeonhole v0.5.18 - duplicate: Users without a home directory can crash with Sieve when using duplicate database. v2.3.17 regression. - imapsieve: When mail was expunged when processing imapsieve events, a crash could occur. Fixes Panic: file mail-index-map.c: line 558 (mail_index_map_lookup_seq_range): assertion failed: (first_uid > 0) - managesieve-login: Proxy didn't support forwarding the forward_* passdb fields. - redirect: Sieve would crash if redirect after keep-equivalent action failed. - sieve: Interpreter crashes when the Sieve index extension is used with index zero. - vnd.dovecot.filter: Envelope sender string may become corrupted when Sieve scripts are using vnd.dovecot.filter. This could end up corrupting mbox's From line and return wrong envelope sender string in ------------------------------------------------------------------- Wed Feb 2 12:28:24 UTC 2022 - Dominique Leuenberger <dimstar@opensuse.org> - Fix dovecot-2.3.0-dont_use_etc_ssl_certs.patch: Align the certificate path/filenames to /etc/ssl/private/*.crt, which happens to match what the patch also does for mkcert.sh (boo#1193909). - Rebase dovecot-2.3.0-better_ssl_defaults.patch ------------------------------------------------------------------- Thu Dec 16 08:14:51 UTC 2021 - Fabian Vogt <fvogt@suse.com> - Update dovecot-2.3.0-dont_use_etc_ssl_certs.patch to also adjust the path in the 10-ssl.conf example (boo#1193758) - Rebase dovecot-2.3.0-better_ssl_defaults.patch ------------------------------------------------------------------- Tue Dec 7 18:54:54 UTC 2021 - Michael Ströder <michael@stroeder.com> - update to 2.3.17.1 and pigeonhole to 0.5.17.1 - rebased dovecot-2.3.0-better_ssl_defaults.patch Dovecot 2.3.17.1 - dsync: Add back accidentically removed parameters. - lib-ssl-iostream: Fix assert-crash when OpenSSL returned syscall error without errno. - master: Dovecot failed to start if ssl_ca was too large. Dovecot 2.3.17 * Dovecot now logs a warning if time seems to jump forward at least 100 milliseconds. * dict: Lines logged by the dict process now contain the dict name as the prefix. * lib-index: mail_cache_fields, mail_always_cache_fields and mail_never_cache_fields now verifies that the listed header names are valid. Especially the UTF8 "–" character has sometimes been wrongly used instead of the ASCII "-". + *-login: Added login_proxy_rawlog_dir setting to capture rawlogs between proxy and backend. + dict: The server process now keeps the last 10 idle dict backends cached for maximum of 30 seconds. Practically this acts as a connection pool for dict-redis and dict-ldap. Note that this doesn't affect dict-sql, because it already had its own internal cache. + doveadm: New stats add/remove commands added to support changing the metrics configuration on runtime. + lazy_expunge: Added lazy_expunge_exclude settings to disable lazy_expunge for specific folders. \Special-use flags can be used as folder names. + lib-lua: Added a new helper function dovecot.restrict_global_variables() to disable or enable defining new global variables. - LAYOUT=index List index rebuild was missing. - LAYOUT=index: Duplicate GUIDs were not detected. - acl: When using acl_ignore_namespace Dovecot attempted to access or create dovecot-acl-list even when the namespace should have been ignored. For virtual namespaces this could have yielded errors about "Read-only file system" or "Permission denied". - auth: Setting the "master" passdb field to empty value would cause proxying to fail with an authentication error. Now an empty "master" field is ignored. - doveadm-server: Duplicate error lines were sent for failed commands. This didn't normally cause visible problems, except when using wildcards in usernames or -A parameter to go through multiple users. - doveadm-server: Logs written by doveadm-server were often missing log prefixes, especially mail_log_prefix for mail commands. Logs sent to doveadm TCP client were also missing log prefixes. - doveadm: v2.3 regression: batch command always crashes. - doveadm: v2.3.11 regression: Commands failed if ssl_cert or ssl_key files weren't readable by the user running doveadm, even though doveadm didn't actually use these settings - imap-hibernate: Process may crash at deinit: Panic: file ioloop.c: line 928 (io_loop_destroy): assertion failed: (ioloop->cur_ctx == NULL). - imap: Using imap_fetch_failure=no-after can cause assert-crash with some IMAP commands if reading the mail fails (e.g. wrong cached mail size). Fixes: Panic: file index-mail-headers.c: line 198 (index_mail_parse_header_init): assertion failed: (!mail->data.header_parser_initialized) - imap: v2.3.10 regression: When using INDEXPVT to enable private \Seen flags (for shared or public namespaces) the STORE command did not send untagged replies for the \Seen flag changes. - imap: v2.3.15 regression: If PREVIEW/SNIPPET is not the final FETCH option in the command, the IMAP FETCH response is broken. - imap: v2.3.15 regression: MOVE command leaks mailbox if it can't be opened and crashes at deinit: Panic: file mail-user.c: line 229 (mail_user_deinit): assertion failed: ((*user)->refcount == 1). - imapc: Copying nonexistent mail via imapc could have crashed. Fixes: Panic: file mail-storage.c: line 2385 (mailbox_transaction_commit_get_changes): assertion failed: (ret < 0 || seq_range_count(&changes_r->saved_uids) == save_count || array_count(&changes_r->saved_uids) == 0). - indexer: v2.3.15 regression: Process crashes if indexer-client disconnects while it's waiting for command reply. This happened for example if IMAP SEARCH triggered long fts indexing and the IMAP client disconnected while waiting for the reply. - indexer: v2.3.15 regression: Process may have crashed in some situations. - indexer: v2.3.15 regression: indexer-worker processes may not have reached the process_limit in some situations, possibly even using just one indexer-worker process even though there were many indexing requests queued. - lib-compression: Reading lz4 compressed mdbox mails may crash. Fixes: Panic: file istream.c: line 345 (i_stream_read_memarea): assertion failed: (!stream->blocking). - lib-compression: bench-compress crashes due to xz being read-only. - lib-lua: Fix linking libdict_lua for non-GNU linkers when Lua support is disabled. - lib-mail: There was no limit on how large an email header name could be. Processable header names are now limited to 1000 bytes. - lib-oauth2: Dovecot disallowed JWT tokens if their validity time was older than token creation time (nbf < iat). - lib-storage: Reduce memory footprint of certain storage operations. - lib-storage: When listing mailboxes with storage name escape characters (^ or .) as part of the mailbox name, the listing could show corrupted mailbox names. Due to an issue in handling escaped parent folders, the listing of other mailbox names would become corrupted by prepending parts of the previously listed mailboxes parent folder as prefix to the actual mailbox names. The corruption can occur when using LAYOUT=INDEX and maildir or obox, or when using the listescape plugin. - mail-crypt: Fix "-O" argument for "doveadm mailbox cryptokey password" command to be a boolean, and not expect a string. - submission-login: Add support for not authenticating to next hop in submission proxying. - submission-login: EHLO was not sent again after XCLIENT when doing submission proxying. - virtual: Mailboxes do not correctly detect underlying mailboxes getting re-created even though they have a different UIDVALIDITY or GUID. Pigeonhole v0.5.17 - duplicate: The Sieve duplicate test is prone to false negatives when the user receives many e-mails concurrently, meaning that duplicate deliveries can still occur. - fileinto: v2.3.16 regression: Sieve delivery crashes if mail is delivered to non-existing and existing folder. - imap-filter-sieve: v2.3.15 regression: The CPU limits on Sieve execution are too easily exceeded in IMAP context (the IMAPSieve and FILTER=SIEVE capabilities). Changed the default to unlimited CPU time for IMAP context, since similar excessive resource usage can be caused by other means as well. The CPU limits on Sieve scripts executed at LDA/LMTP delivery are still enforced by default. - redirect: The Sieve redirect action has protections against users triggering mail loops. Unfortunately, the detection of a redirect mail loop sometimes causes the message to get lost if no other Sieve action is applied that delivers the message somewhere else. - redirect: v2.3.16 regression: With certain Sieve scripts if redirect fails due to temporary failure, the lmtp process may crash after the delivery. Fixes: Panic: file mail-user.c: line 229 (mail_user_deinit): assertion failed: ((*user)->refcount == 1). ------------------------------------------------------------------- Tue Aug 10 22:38:15 UTC 2021 - Michael Ströder <michael@stroeder.com> - added back-port fix mail-cache-bigendian.diff - update to 2.3.16 and pigeonhole to 0.5.16: Dovecot 2.3.16 * Any unexpected exit() will now result in a core dump. This can especially help notice problems when a Lua script causes exit(0). * auth-worker process is now restarted when the number of auth requests reaches service auth-worker { service_count }. The default is still unlimited. + Event improvements: Added data_stack_grow event and http-client category. See https://doc.dovecot.org/admin_manual/list_of_events/ + oauth2: Support RFC 7628 openid-configuration element. This allows clients to support OAUTH2 for any server, not just a few hardcoded servers like they do now. See openid_configuration_url setting in dovecot-oauth2.conf.ext. + mysql: Single statements are no longer enclosed with BEGIN/COMMIT. + dovecot-sysreport --core supports multiple core files now and does not require specifying the binary path. + imapc: When imap_acl plugin is loaded and imapc_features=acl is used, IMAP ACL commands are proxied to the remote server. See https://doc.dovecot.org/configuration_manual/mail_location/imapc/ + dict-sql now supports the "UPSERT" syntax for SQLite and PostgreSQL. + imap: If IMAP client disconnects during a COPY command, the copying is aborted, and changes are reverted. This may help to avoid many email duplicates if client disconnects during COPY and retries it after reconnecting. - master process was using 100% CPU if service attempted to create more processes due to process_min_avail, but process_limit was already reached. v2.3.15 regression. - Using attachment detection flags wrongly logged unnecessary "Failed to add attachment keywords" errors. v2.3.13 regression. - IMAP QRESYNC: Expunging UID 1 mail resulted in broken VANISHED response, which could have confused IMAP clients. v2.3.13 regression. - imap: STORE didn't send untagged replies for \Seen changes for (shared) mailboxes using INDEXPVT. v2.3.10 regression. - rawlog_dir setting would not log input that was pipelined after authentication command. - Fixed potential infinite looping with autoexpunging. - Log event exporter: Truncate long fields to 1000 bytes - LAYOUT=index: ACL inheritance didn't work when creating mailboxes - Event filters: Unquoted '?' wildcard caused a crash at startup - fs-metawrap: Fix to handling zero sized files - imap-hibernate: Fixed potential crash at deinit. - acl: dovecot-acl-list files were written for acl_ignore_namespaces - program-client (used by Sieve extprograms, director_flush_socket) may have missed status response from UNIX and network sockets, resulting in unexpected failures. Pigeonhole v0.5.16 * .dovecot.sieve.log file now includes year in the header. * Change Sieve script result execution to delay definitive action execution to the end of a successful Sieve script execution session. This is part of an effort to solve problems with the Sieve duplicate test. As a side-effect, some rare temporary-error cases yield different results, in which partial failure is more likely. ------------------------------------------------------------------- Tue Jun 22 15:13:47 UTC 2021 - Marcus Rueckert <mrueckert@suse.de> - use lua 5.1 for sle12 ------------------------------------------------------------------- Mon Jun 21 11:27:29 UTC 2021 - Michael Ströder <michael@stroeder.com> - update to 2.3.15 and pigeonhole to 0.5.15: * security fixes for CVE-2021-29157, CVE-2021-33515, and CVE-2020-28200 * rebased patch dovecot-2.3.0-better_ssl_defaults.patch * removed obsolete back-port patches allow-tls1.3-only.patch and openssl-cnf-default_bits-2048.patch * require lua53-devel for build Dovecot 2.3.15 * CVE-2021-29157: Dovecot does not correctly escape kid and azp fields in JWT tokens. This may be used to supply attacker controlled keys to validate tokens, if attacker has local access. * CVE-2021-33515: On-path attacker could have injected plaintext commands before STARTTLS negotiation that would be executed after STARTTLS finished with the client. * Disconnection log messages are now more standardized across services. They also always now start with "Disconnected" prefix. * Dovecot now depends on libsystemd for systemd integration. * Removed support for Lua 5.2. Use version 5.1 or 5.3 instead. * config: Some settings are now marked as "hidden". It's discouraged to change these settings. They will no longer be visible in doveconf output, except if they have been changed or if doveconf -s parameter is used. See https://doc.dovecot.org/settings/advanced/ for details. * imap-compress: Compression level is now algorithm specific. See https://doc.dovecot.org/settings/plugin/compress-plugin/ * indexer-worker: Convert "Indexed" info logs to an event named "indexer_worker_indexing_finished". See https://doc.dovecot.org/admin_manual/list_of_events/#indexer-worker-indexing-finished + Add TSLv1.3 support to min_protocols. + Allow configuring ssl_cipher_suites. (for TLSv1.3+) + acl: Add acl_ignore_namespace setting which allows to entirely ignore ACLs for the listed namespaces. + imap: Support official RFC8970 preview/snippet syntax. Old methods of retrieving preview information via IMAP commands ("SNIPPET and PREVIEW with explicit algorithm selection") have been deprecated. + imapc: Support INDEXPVT for imapc storage to enable private message flags for cluster wide shared mailboxes. + lib-storage: Add new events: mail_opened, mail_expunge_requested, mail_expunged, mail_cache_lookup_finished. See https://doc.dovecot.org/admin_manual/list_of_events/#mail + zlib, imap-compression, fs-compress: Support compression levels that the algorithm supports. Before, we would allow hardcoded value between 1 to 9 and would default to 6. Now we allow using per-algorithm value range and default to whatever default the algorithm specifies. - *-login: Commands pipelined together with and just after the authenticate command cause these commands to be executed twice. This applies to all protocols that involve user login, which currently comprises of imap, pop3, submisision and managesieve. - *-login: Processes are supposed to disconnect the oldest non-logged in connection when process_limit was reached. This didn't actually happen with the default "high-security mode" (with service_count=1) where each connection is handled by a separate process. - *-login: When login process reaches client/process limits, oldest client connections are disconnected. If one of these was still doing anvil lookup, this caused a crash. This could happen only if the login process limits were very low or if the server was overloaded. - Fixed building with link time optimizations (-flto). - auth: Userdb iteration with passwd driver does not always return all users with some nss drivers. - dsync: Shared INBOX not synced when "mail_shared_explicit_inbox" was disabled. If a user has a shared mailbox which is another user's INBOX, dsync didn't include the mailbox in syncing unless explicit naming is enabled with "mail_shared_explicit_inbox" set to "yes". - dsync: Shared namespaces were not synced with "-n" flag. - dsync: Syncing shared INBOX failed if mail_attribute_dict was not set. If a user has a shared mailbox that is another user's INBOX, dsync failed to export the mailbox if mail attributes are disabled. - fts-solr, fts-tika: Using both Solr FTS and Tika may have caused HTTP requests to assert-crash: Panic: file http-client-request.c: line 1232 (http_client_request_send_more): assertion failed: (req->payload_input != NULL) - fts-tika: 5xx errors returned by Tika server as indexing failures. However, Tika can return 5xx for some attachments every time. So the 5xx error should be retried once, but treated as success if it happens on the retry as well. v2.3 regression. - fts-tika: v2.3.11 regression: Indexing messages with fts-tika may have resulted in Panic: file message-parser.c: line 802 (message_parser_deinit_from_parts): assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input)) - imap: SETMETADATA could not be used to unset metadata values. Instead NIL was handled as a "NIL" string. v2.3.14 regression. - imap: IMAP BINARY FETCH crashes at least on empty base64 body: Panic: file index-mail-binary.c: line 358 (blocks_count_lines): assertion failed: (block_count == 0 || block_idx+1 == block_count) - imap: If IMAP client using the NOTIFY command was disconnected while sending FETCH notifications to the client, imap could crash with Panic: Trying to close mailbox INBOX with open transactions. - imap: Using IMAP COMPRESS extension can cause IMAP connection to hang when IMAP commands are >8 kB long. - imapc: If remote server sent BYE but didn't immediately disconnect, it could cause infinite busy-loop. - lib-index: Corrupted cache record size in dovecot.index.cache file could have caused a crash (segfault) when accessing it. - lib-oauth2: JWT token time validation now works correctly with 32-bit systems. - lib-ssl-iostream: Checking hostnames against an SSL certificate was case-sensitive. - lib-storage: Corrupted mime.parts in dovecot.index.cache may have resulted in Panic: file imap-bodystructure.c: line 206 (part_write_body): assertion failed: (text == ((part->flags & MESSAGE_PART_FLAG_TEXT) != 0)) - lib-storage: Index rebuilding (e.g. via doveadm force-resync) didn't preserve the "hdr-pop3-uidl" header. Because of this, the next pop3 session could have accessed all of the emails' metadata to read their POP3 UIDL (opening dbox files). - listescape: When using the listescape plugin and a shared namespace the plugin didn't work properly anymore resulting in errors like: "Invalid mailbox name: Name must not have '/' character." - lmtp: Connection crashes if connection gets disconnected due to multiple bad commands and the last bad command is BDAT. - lmtp: The Dovecot-specific LMTP parameter XRCPTFORWARD was blindly forwarded by LMTP proxy without checking that the backend has support. This caused a command parameter error from the backend if it was running an older Dovecot release. This could only occur in more complex setups where the message was proxied twice; when the proxy generated the XRCPTFORWARD parameter itself the problem did not occur, so this only happened when it was forwarded. - lmtp: The LMTP proxy crashes with a panic when the remote server replies with an error while the mail is still being forwarded through a DATA/BDAT command. - lmtp: Username may have been missing from lmtp log line prefixes when it was performing autoexpunging. - master: Dovecot would incorrectly fail with haproxy 2.0.14 service checks. - master: Systemd service: Dovecot announces readiness for accepting connections earlier than it should. The following environment variables are now imported automatically and can be omitted from import_environment setting: NOTIFY_SOCKET LISTEN_FDS LISTEN_PID. - master: service { process_min_avail } was launching processes too slowly when master was forking a lot of processes. - util: Make the health-check.sh example script POSIX shell compatible. Pigeonhole 0.5.15 * CVE-2020-28200: Sieve interpreter is not protected against abusive scripts that claim excessive resource usage. Fixed by limiting the user CPU time per single script execution and cumulatively over several script runs within a configurable timeout period. Sufficiently large CPU time usage is summed in the Sieve script binary and execution is blocked when the sum exceeds the limit within that time. The block is lifted when the script is updated after the resource usage times out. * Disconnection log messages are now more standardized across services. They also always now start with "Disconnected" prefix. - managesieve: Commands pipelined together with and just after the authenticate command cause these commands to be executed twice. ------------------------------------------------------------------- Fri May 14 10:07:07 UTC 2021 - Fabian Vogt <fvogt@suse.com> - Add patch to fix insecure default openssl.cnf (boo#1184552): * openssl-cnf-default_bits-2048.patch - Use %autosetup ------------------------------------------------------------------- Thu Mar 4 10:28:11 UTC 2021 - Michael Ströder <michael@stroeder.com> - update to 2.3.14 and pigeonhole to 0.5.14 * removed obsolete fix-timeval_cmp_margin-for-32bit-systems.patch Dovecot 2.3.14 * Added new aliases for some variables. Usage of the old ones is possible, but discouraged. (These were partially added already to v2.3.13.) See https://doc.dovecot.org/configuration_manual/config_file/config_variables/ for more information. * Optimize imap/pop3/submission/managesieve proxies to use less CPU at the cost of extra memory usage. * Remove autocreate, expire, snarf and mail-filter plugins. * Remove cydir storage driver. * Remove XZ/LZMA write support. Read support will be removed in future release. * doveadm -D: Add timestamps to debug output even when LOG_STDERR_TIMESTAMP environment variable is not set. Timestamp format is taken from log_timestamp setting. * If BROKENCHAR or listescape plugin is used, the escaped folder names may be slightly different from before in some situations. This is unlikely to cause issues, although caching clients may redownload the folders. * imapc: It now enables BROKENCHAR=~ by default to escape remote folder names if necessary. This also means that if there are any '~' characters in the remote folder names, they will be visible as "~7e". * imapc: When using local index files folder names were escaped on filesystem a bit differently. This affects only if there are folder names that actually require escaping, which isn't so common. The old style folders will be automatically deleted from filesystem. * stats: Update exported metrics to be compliant with OpenMetrics standard. + doveadm: Add an optional '-p' parameter to metadata list command. If enabled, "/private", and "/shared" metadata prefixes will be prepended to the keys in the list output. + doveconf: Support environment variables in config files. See https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax/#environment-variables for more details. + indexer-worker: Change indexer to disconnect from indexer-worker after each request. This allows service indexer-worker's service_count & idle_kill settings to work. These can be used to restart indexer-worker processes once in a while to reduce their memory usage. - auth: "nodelay" with various authentication mechanisms such as apop and digest-md5 crashed AUTH process if authentication failed. - auth: Auth lua script generating an error triggered an assertion failure: Panic: file db-lua.c: line 630 (auth_lua_call_password_verify): assertion failed: (lua_gettop(script->L) == 0). - configure: Fix libunwind detection to work on other than x86_64 systems. - doveadm-server: Process could crash if logging was done outside command handling. For example http-client could have done debug logging afterwards, resulting in either segfault or Panic: file http-client.c: line 642 (http_client_context_close): assertion failed: (cctx->clients_list == NULL). - dsync: Folder name escaping with BROKENCHAR didn't work completely correctly. This especially caused problems with dsync-migrations using imapc where some of the remote folder names may not have been accessible. - dsync: doveadm sync + imapc doesn't always sync all mails when doing an incremental sync (-1), which could lead to mail loss when it's used for migration. This happens only when GUIDs aren't used (i.e. imapc without imapc_features=guid-forced). - fts-tika: When tika server returns error, some mails cause Panic: file message-parser.c: line 802 (message_parser_deinit_from_parts): assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input)) - lib-imap: imapc parsing illegal BODYSTRUCTUREs with NILs could have resulted in crashes. This exposed that Dovecot was wrongly accepting atoms in "nstring" handling. Changed the IMAP parsing to be more strict about this now. - lib-index: If dovecot.index.cache has corrupted message size, fetching BODY/BODYSTRUCTURE may cause assert-crash: Panic: file index-mail.c: line 1140 (index_mail_parse_body_finish): assertion failed: (mail->data.parts != NULL). - lib-index: Minor error handling and race condition fixes related to rotating dovecot.index.log. These didn't usually cause problems, unless the log files were rotated rapidly. - lib-lua: Lua scripts using coroutines or lua libraries using coroutines (e.g., cqueues) panicked. - Message PREVIEW handled whitespace wrong so first space would get eaten from between words. - FTS and message PREVIEW (snippet) parsed HTML &entities case-sensitively. - lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE was written in a way that may have caused confusion for IMAP clients and also Dovecot itself when parsing it. The truncated part is now written out using application/octet-stream MIME type. - lib-oauth2: HS512 and HS384 JWT token algorithms crash when you try to use them: Panic: file hmac.c: line 26 (hmac_init): assertion failed: (meth->context_size <= MAC_MAX_CONTEXT_SIZE). - event filters: NOT keyword did not have the correct associativity. NOT a AND b were getting parsed as NOT (a AND b) instead of (NOT a) AND b. - Ignore ECONNRESET when closing socket. This avoids logging useless errors on systems like FreeBSD. - event filters: event filter syntax error may lead to Panic: file event-filter.c: line 137 (event_filter_parse): assertion failed: (state.output == NULL) - lib: timeval_cmp_margin() was broken on 32-bit systems. This could potentially have caused HTTP timeouts to be handled incorrectly. - log: instance_name wasn't used as syslog ident by the log process. - master: After a service reached process_limit and client_limit, it could have taken up to 1 second to realize that more client connections became available. During this time client connections could have been unnecessarily rejected and a warning logged: Warning: service(...): process_limit (...) reached, client connections are being dropped - stats: Crash would occur when generating openmetrics data for metrics using aggregating functions. - stats: Event filters comparing against empty strings crash the stats process. Pigeonhole 0.5.14 * IMAP FILTER command: cmd-filter-sieve - Do not allow NIL as script name argument. ------------------------------------------------------------------- Thu Feb 4 07:06:00 UTC 2021 - Arjen de Korte <suse+build@de-korte.org> - add BuildRequires openssl-devel >= 1.0.1 - add fix-timeval_cmp_margin-for-32bit-systems.patch Fix timeval_cmp_margin for 32-bit systems https://github.com/dovecot/core/pull/149 ------------------------------------------------------------------- Mon Jan 4 12:16:00 UTC 2021 - Arjen de Korte <suse+build@de-korte.org> - update to 2.3.13 and pigeonhole to 0.5.13 Dovecot 2.3.13 * CVE-2020-24386: Specially crafted command can cause IMAP hibernate to allow logged in user to access other people's emails and filesystem information. * Metric filter and global event filter variable syntax changed to a SQL-like format. See https://doc.dovecot.org/configuration_manual/event_filter/ * auth: Added new aliases for %{variables}. Usage of the old ones is possible, but discouraged. * auth: Removed RPA auth mechanism, SKEY auth mechanism, NTLM auth mechanism and related password schemes. * auth: Removed passdb-sia, passdb-vpopmail and userdb-vpopmail. * auth: Removed postfix postmap socket + auth: Added new fields for auth server events. These fields are now also available for all auth events. See https://doc.dovecot.org/admin_manual/list_of_events/#authentication-server for details. + imap-hibernate: Added imap_client_hibernated, imap_client_unhibernated and imap_client_unhibernate_retried events. See https://doc.dovecot.org/admin_manual/list_of_events/ for details. + lib-index: Added new mail_index_recreated event. See https://doc.dovecot.org/admin_manual/list_of_events/#mail-index-recreated + lib-sql: Support TLS options for cassandra driver. This requires cpp-driver v2.15 (or later) to work reliably. + lib-storage: Missing $HasAttachment / $HasNoAttachment flags are now added to existing mails if mail_attachment_detection_option=add-flags and it can be done inexpensively. + login proxy: Added login_proxy_max_reconnects setting (default 3) to control how many reconnections are attempted. + login proxy: imap/pop3/submission/managesieve proxying now supports reconnection retrying on more than just connect() failure. Any error except a non-temporary authentication failure will result in reconnect attempts. - auth: Lua passdb/userdb leaks stack elements per call, eventually causing the stack to become too deep and crashing the auth or auth-worker process. - auth: SASL authentication PLAIN mechanism could be used to trigger read buffer overflow. However, this doesn't seem to be exploitable in any way. - auth: v2.3.11 regression: GSSAPI authentication fails because dovecot disallows NUL bytes for it. - dict: Process used too much CPU when iterating keys, because each key used a separate write() syscall. - doveadm-server: Crash could occur if logging was done outside command handling. For example http-client could have done debug logging afterwards, resulting in either segfault or Panic: file http-client.c: line 642 (http_client_context_close): assertion failed: (cctx->clients_list == NULL). - doveadm-server: v2.3.11 regression: Trying to connect to doveadm server process via starttls assert-crashed if there were no ssl=yes listeners: Panic: file master-service-ssl.c: line 22 (master_service_ssl_init): assertion failed: (service->ssl_ctx_initialized). - fts-solr: HTTP requests may have assert-crashed: Panic: file http-client-request.c: line 1232 (http_client_request_send_more): assertion failed: (req->payload_input != NULL) - imap: IMAP NOTIFY could crash with a segmentation fault due to a bad configuration that causes errors. Sending the error responses to the client can cause the segmentation fault. This can for example happen when several namespaces use the same mail storage location. - imap: IMAP NOTIFY used on a shared namespace that doesn't actually exist (e.g. public namespace for a nonexistent user) can crash with a panic: Panic: Leaked view for index /tmp/home/asdf/mdbox/dovecot.list.index: Opened in (null):0 - imap: IMAP session can crash with QRESYNC extension if many changes are done before asking for expunged mails since last sync. - imap: Process might hang indefinitely if client disconnects after sending some long-running commands pipelined, for example FETCH+LOGOUT. - lib-compress: Mitigate crashes when configuring a not compiled in compression. Errors with compression configuration now distinguish between not supported and unknown. - lib-compression: Using xz/lzma compression in v2.3.11 could have written truncated output in some situations. This would result in "Broken pipe" read errors when trying to read it back. - lib-compression: zstd compression could have crashed in some situations: Panic: file ostream.c: line 287 (o_stream_sendv_int): assertion failed: (!stream->blocking) - lib-dict: dict client could have crashed in some rare situations when iterating keys. - lib-http: Fix several assert-crashes in HTTP client. - lib-index: v2.3.11 regression: When mails were expunged at the same time as lots of new content was being saved to the cache (e.g. cache file was lost and is being re-filled) a deadlock could occur with dovecot.index.cache / dovecot.index.log. - lib-index: v2.3.11 regression: dovecot.index.cache file was being purged (rewritten) too often when it had a field that hadn't been accessed for over 1 month, but less than 2 months. Every cache file change caused a purging in this situation. - lib-mail: MIME parts were not returned correctly by Dovecot MIME parser. Regression caused by fixing CVE-2020-12100. - lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE was written in a way that may have caused confusion for both IMAP clients and Dovecot itself when parsing it. The truncated part is now written out using application/octet-stream MIME type. - lib-mail: v2.3.11 regression: Mail delivery / parsing crashed when the 10000th MIME part was message/rfc822 (or if parent was multipart/digest): Panic: file message-parser.c: line 167 (message_part_append): assertion failed: (ctx->total_parts_count <= ctx->max_total_mime_parts). - lib-oauth2: Dovecot incorrectly required oauth2 server introspection reply to contain username with invalid token. - lib-ssl-iostream, lib-dcrypt: Fix building with OpenSSL that has deprecated APIs disabled. - lib-storage: When mail's size is different from the cached one (in dovecot.index.cache or Maildir S=size in the filename), this is handled by logging "Cached message size smaller/larger than expected" error. However, in some situations this also ended up crashing with: Panic: file istream.c: line 315 (i_stream_read_memarea): assertion failed: (old_size <= _stream->pos - _stream->skip). - lib-storage: v2.3 regression: Copying/moving mails was taking much more memory than before. This was mainly visible when copying/moving thousands of mails in a single transaction. - lib-storage: v2.3.11 regression: Searching messages assert-crashed (without FTS): Panic: file message-parser.c: line 174 (message_part_finish): assertion failed: (ctx->nested_parts_count > 0). - lib: Dovecot v2.3 moved signal handlers around in ioloops, causing more CPU usage than in v2.2. - lib: Fixed JSON parsing: '\' escape sequence may have wrongly resulted in error if it happened to be at read boundary. Any NUL characters and '\u0000' will now result in parsing error instead of silently truncating the data. - lmtp, submission: Server may hang if SSL client connection disconnects during the delivery. If this happened repeated, it could have ended up reaching process_limit and preventing any further lmtp/submission deliveries. - lmtp: Proxy does not always properly log TLS connection problems as errors; in some cases, only a debug message is logged if enabled. - lmtp: The LMTP service can hang when commands are pipelined. This can particularly occur when one command in the middle of the pipeline fails. One example of this occurs for proxied LMTP transactions in which the final DATA or BDAT command is pipelined after a failing RCPT command. - login-proxy: The login_source_ips setting has no effect, and therefore the proxy source IPs are not cycled through as they should be. - master: Process was using 100% CPU in some situations when a broken service was being throttled. - pop3-login: POP3 login would fail with "Input buffer full" if the initial response for SASL was too long. - stats: Crash would occur when generating openmetrics data for metrics using aggregating functions. Pigeonhole 0.5.13 - duplicate: The test was handled badly in a multiscript (sieve_before, sieve_after) scenario in which an earlier script in the sequence with a duplicate test succeeded, while a later script caused a runtime failure. In that case, the message is recorded for duplicate tracking, while the message may not actually have been delivered in the end. - editheader: Sieve interpreter entered infinite loop at startup when the "editheader" configuration listed an invalid header name. This problem can only be triggered by the administrator. - relational: The Sieve relational extension can cause a segfault at compile time. This is triggered by invalid script syntax. The segfault happens when this match type is the last argument of the test command. This situation is not possible in a valid script; positional arguments are normally present after that, which would prevent the segfault. - sieve: For some Sieve commands the provided mailbox name is not properly checked for UTF-8 validity, which can cause assert crashes at runtime when an invalid mailbox name is encountered. This can be caused by the user by writing a bad Sieve script involving the affected commands ("mailboxexists", "specialuse_exists"). This can be triggered by the remote sender only when the user has written a Sieve script that passes message content to one of the affected commands. - sieve: Large sequences of 8-bit octets passed to certain Sieve commands that create or modify message headers that allow UTF-8 text (vacation, notify and addheader) can cause the delivery or IMAP process (when IMAPSieve is used) to enter a memory-consuming semi-infinite loop that ends when the process exceeds its memory limits. Logged in users can cause these hangs only for their own processes. - drop upstreamed patches: - dovecot-2.3.11.3-ftbfs1.patch - dovecot-2.3.11.3-ftbfs2.patch - dovecot-2.3.11.3-gssapi-nul.patch ------------------------------------------------------------------- Tue Nov 24 07:59:06 UTC 2020 - Guillaume GARDET <guillaume.gardet@opensuse.org> - Fix test on 32-bit: * dovecot-2.3.11.3-ftbfs1.patch * dovecot-2.3.11.3-ftbfs2.patch ------------------------------------------------------------------- Wed Nov 4 15:29:48 UTC 2020 - Thorsten Kukuk <kukuk@suse.com> - dovecot is already creating the user accounts, no need to duplicate the code as this package does not need them. - Don't hard require systemd ------------------------------------------------------------------- Tue Sep 15 10:26:44 UTC 2020 - Arjen de Korte <suse+build@de-korte.org> - add dovecot-2.3.11.3-gssapi-nul.patch: Fix for bug introduced in v2.3.11.3.

This mainly affected large XCLIENT commands or a large SASL initial response parameter in the AUTH command. - pop3: pop3_deleted_flag setting was broken, causing: Panic: file seq-range-array.c: line 472 (seq_range_array_invert): assertion failed: (range[count-1].seq2 <= max_seq) Dovecot 2.3.11.2 - auth: Lua passdb/userdb leaks stack elements per call, eventually causing the stack to become too deep and crashing the auth or auth-worker process. - lib-mail: v2.3.11 regression: MIME parts not returned correctly by Dovecot MIME parser. - pop3-login: Login would fail with "Input buffer full" if the initial response for SASL was too long. Dovecot 2.3.11 * CVE-2020-12100: Parsing mails with a large number of MIME parts could have resulted in excessive CPU usage or a crash due to running out of stack memory. * CVE-2020-12673: Dovecot's NTLM implementation does not correctly check message buffer size, which leads to reading past allocation which can lead to crash. * CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an address that has the empty quoted string as local-part causes the lmtp service to crash. * CVE-2020-12674: Dovecot's RPA mechanism implementation accepts zero-length message, which leads to assert-crash later on. * Events: Fix inconsistency in events. See event documentation in https://doc.dovecot.org. * imap_command_finished event's cmd_name field now contains "unknown" for unknown commands. A new "cmd_input_name" field contains the command name exactly as it was sent. * lib-index: Renamed mail_cache_compress_* settings to mail_cache_purge_*. Note that these settings are mainly intended for testing and usually shouldn't be changed. * events: Renamed "index" event category to "mail-index". * events: service:<name> category is now using the name from configuration file. * dns-client: service dns_client was renamed to dns-client. * log: Prefixes generally use the service name from configuration file. For example dict-async service will now use "dict-async(pid): " log prefix instead of "dict(pid): " * *-login: Changed logging done by proxying to use a consistent prefix containing the IP address and port. * *-login: Changed disconnection log messages to be slightly clearer. + dict: Add events for dictionaries. + lib-index: Finish logging with events. + oauth2: Support local validation of JWT tokens. + stats: Add support for dynamic histograms and grouping. See https://doc.dovecot.org/configuration_manual/stats/. + imap: Implement RFC 8514: IMAP SAVEDATE + lib-index: If a long-running transaction (e.g. SORT/FETCH on a huge folder) adds a lot of data to dovecot.index.cache file, commit those changes periodically to make them visible to other concurrent sessions as well. + stats: Add OpenMetrics exporter for statistics. See https://doc.dovecot.org/configuration_manual/stats/openmetrics/. + stats: Support disabling stats-writer socket by setting stats_writer_socket_path="". - auth-worker: Process keeps slowly increasing its memory usage and eventually dies with "out of memory" due to reaching vsz_limit. - auth: Prevent potential timing attacks in authentication secret comparisons: OAUTH2 JWT-token HMAC, imap-urlauth token, crypt() result. - auth: Several auth-mechanisms allowed input to be truncated by NUL which can potentially lead to unintentional issues or even successful logins which should have failed. - auth: When auth policy returned a delay, auth_request_finished event had policy_result=ok field instead of policy_result=delayed. - auth: auth process crash when auth_policy_server_url is set to an invalid URL. - dict-ldap: Crash occurs if var_expand template expansion fails. - dict: If dict client disconnected while iteration was still running, dict process could have started using 100% CPU, although it was still handling clients. - doveadm: Running doveadm commands via proxying may hang, especially when doveadm is printing a lot of output. - imap: "MOVE * destfolder" goes to a loop copying the last mail to the destination until the imap process dies due to running out of memory. - imap: Running "UID MOVE 1:* Trash" on an empty folder goes to infinite loop. - imap: SEARCH doesn't support $. - lib-compress: Buffer over-read in zlib stream read. - lib-dns: If DNS lookup times out, lib-dns can cause crash in calling process. - lib-index: Fixed several bugs in dovecot.index.cache handling that could have caused cached data to be lost. - lib-index: Writing to >=1 GB dovecot.index.cache files may cause assert-crashes: Panic: file mail-index-util.c: line 37 (mail_index_uint32_to_offset): assertion failed: (offset < 0x40000000) - lib-ssl-iostream: Fix buggy OpenSSL error handling without assert-crashing. If there is no error available, log it as an error instead of crashing: Panic: file iostream-openssl.c: line 599 (openssl_iostream_handle_error): assertion failed: (errno != 0) - lib-ssl-iostream: ssl_key_password setting did not work. - submission: A segfault crash may occur when the client or server disconnects while a non-transaction command like NOOP or VRFY is still being processed. - virtual: Copying/moving mails with IMAP into a virtual folder assert-crashes: Panic: file cmd-copy.c: line 152 (fetch_and_copy): assertion failed: (copy_ctx->copy_count == seq_range_count(©_ctx->saved_uids)) Pigeonhole 0.5.11 * managesieve: managesieve_max_line_length setting is now a "size" type instead of just number of bytes. This allows using e.g. "64k" as the value. - lib-sieve: When folding white space is used in the Message-ID header, it is not stripped away correctly before the message ID value is used, causing e.g. garbled log lines at delivery. ------------------------------------------------------------------- Tue May 19 12:04:55 UTC 2020 - Marcus Rueckert <mrueckert@suse.de> - update tls 1.3 patch to allow building with tls 1.0 ------------------------------------------------------------------- Mon May 18 14:04:52 UTC 2020 - Michael Ströder <michael@stroeder.com> - update to 2.3.10.1 with security fixes for * CVE-2020-10957: lmtp/submission: A client can crash the server by sending a NOOP command with an invalid string parameter. (boo#1171457) * CVE-2020-10958: lmtp/submission: Sending many invalid or unknown commands can cause the server to access freed memory, which can lead to a server crash. (boo#1171458) * CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an address that has the empty quoted string as local-part causes the lmtp service to crash. (boo#1171456) ------------------------------------------------------------------- Wed Apr 29 21:25:30 UTC 2020 - Marcus Rueckert <mrueckert@suse.de> - add allow-tls1.3-only.patch: Allow setting TLSv1.3 as minimum TLS version https://github.com/dovecot/core/pull/126 ------------------------------------------------------------------- Fri Mar 6 11:14:00 UTC 2020 - Arjen de Korte <suse+build@de-korte.org> - update to 2.3.10 and pigeonhole to 0.5.10 Dovecot 2.3.10 * Disable retpoline migitations by default. These can cause severe performance regressions, so they should be only enabled when applicable. * IMAP MOVE now commits transactions in batches of 1000 mails. This helps especially with lazy_expunge when moving a lot of mails. It mainly avoids situations where multiple IMAP sessions are running the same MOVE command and duplicating the mails in the lazy_expunge folder. With this change there can still be some duplication, but the MOVE always progresses forward. Also if the MOVE fails at some point, the changes up to the last 1000 mails are still committed instead of rolled back. Note that the COPY command behavior hasn't changed, because it is required by IMAP standard to be an atomic operation. * IMAP EXPUNGE and CLOSE now expunges mails in batches of 1000 mails. This helps especially with lazy_expunge when expunging a lot of mails (e.g. millions) to make sure that the progress always moves forward even if the process is killed. * Autoexpunging now expunges mails in batches of 1000 mails. This helps especially with lazy_expunge when expunging a lot of mails (e.g. millions) to make sure that the progress always moves forward even if the process is killed. + Add tool for generating sysreport called dovecot-sysreport. This generates a bundle of information usually needed for support requests. + Add support for the new IMAP \Important SPECIAL-USE flag (RFC 8457). + Add metric { group_by } setting. This allows automatically creating new metrics based on the fields you want to group statistics by. NOTE: This feature is considered experimental and syntax is subject to change in future release. + auth: Support SCRAM-SHA-256 authentication mechanism. + imap: Support the new IMAP STATUS=SIZE extension. + Use TCP_QUICKACK to reduce latency for some TCP connections. + quota-status: Made the service more robust against erroneous use with Postfix ACL policies other than smtpd_recipient_restrictions. + Add "revision" field support to imap_id_send setting. Using "revision *" will send in IMAP ID command response the short commit hash of the Dovecot git source tree HEAD (same as in dovecot --version). + IMAP ENVELOPE includes now all addresses when there are multiple headers (From, To, Cc, etc.) The standard way of having multiple addresses is to just list them all in a single header. It's non-standard to have multiple headers. However, since MTAs allow these mails to pass through and different software may handle them in different ways, it's better from security point of view to show all the addresses. + Event filters now support using "field_name=" to match a field that doesn't exist or has an empty value. For example use "error=" to match only events that didn't fail. - acl: INBOX ACLs shouldn't apply for IMAP GETMETADATA/SETMETADATA commands. - cassandra: CASS_ERROR_SERVER_WRITE_FAILURE error should also be treated as "uncertain write failure". - dict-redis: Using quota_clone configured with dict-redis could have crashed when Redis responded slowly. - fts-solr: The XML response parser fails to parse large/chunked responses correctly. This leads to spurious parse errors, most notably: "Error: fts_solr: received invalid uid '0'". - imap-hibernate: Communication trouble with imap-master leads to segfault. - imap-hibernate: Unhibernation retrying wasn't working. - imap: Fixed auth lookup privilege problem when imap process was reused and user was being un-hibernated. - Fix potential crash when copying/moving mails within the same folder. This happened only when there were a lot of fields in dovecot.index.cache. - lib-index: Recreating dovecot.index.cache file could have crashed when merging bitmask fields. - lib-index: Using public/shared folders with INDEXPVT configured to use private \Seen flags, trying to search seen/unseen in an empty folder crashes with segfault. - lib-mail: Large base64-encoded mails weren't decoded properly. This could have affected searching/indexing mails and message snippet generation. - lib-mail: Message with only quoted text could have caused message snippet to ignore its 200 character limit and return the entire message. This was added also to dovecot.index.cache file, which increased disk space and memory usage unnecessarily. v2.3.9.2 regression (previous versions cached the quoted snippet as empty). In a large mail quoted text could have become wrongly added to the snippet, possibly mixed together with non-quoted text. - lib-smtp: client could have assert-crashed if STARTTLS handshake finished earlier than usually. - lib-ssl-iostream: remove -static flag for lib-ssl-iostream linking to prevent a compile issue. - lib-storage: Mailbox synchronization may have assert-crashed in some rare situations. - lib-storage: mdbox didn't preserve date.saved with dsync. - lib: Don't require EAI_{ADDRFAMILY,NODATA}, breaks FreeBSD - master: Some services could respawn unthrottled if they crash during startup. - push-notification: Do not send push_notification_finished event if nothing was done. This happens when mail transaction is started and ended with no changes. - quota-status: Addresses with special characters in the local part caused problems in the interaction between Postfix and Dovecot. Postfix sent its own internal representation in the recipient field, while Dovecot expected a valid RFC5321 mailbox address. - submission-login: SESSION was not correctly encoded field for the XCLIENT command. Particularly, a '+' character introduced by the session ID's Base64 encoding causes problems. - submission: Fix submission_max_mail_size to work correctly on 32-bit systems. - submission: Trusted connections crashed in second connection's EHLO if submission-login { service_count } is something else than 1 (which is the default). - submission: XCLIENT command was never used in the protocol exchange with the relay MTA when submission_backend_capabilities is configured, even when the relay MTA was properly configured to accept the XCLIENT command. Pigeonhole 0.5.10 * imap_sieve_filter: Change result action logging to include IMAP UID - vacation: Addresses were compared case-sensitively. ------------------------------------------------------------------- Wed Feb 26 12:40:54 UTC 2020 - Dominique Leuenberger <dimstar@opensuse.org> - Update dovecot-2.3.0-dont_use_etc_ssl_certs.patch: since we change CERTDIR to /etc/ssl/private, it is rather evil to then err out claiming /etc/ssl/certs would not exist. The error message should mention the directory it tested for. ------------------------------------------------------------------- Wed Feb 12 12:24:46 UTC 2020 - Arjen de Korte <suse+build@de-korte.org> - update to 2.3.9.3 * CVE-2020-7046: Truncated UTF-8 can be used to DoS submission-login and lmtp processes. * CVE-2020-7957: Specially crafted mail can crash snippet generation. ------------------------------------------------------------------- Sun Dec 22 19:51:09 UTC 2019 - Peter Varkoly <varkoly@suse.com> - Adapt package changes in mysql-devel ------------------------------------------------------------------- Sat Dec 14 08:55:56 UTC 2019 - Michael Ströder <michael@stroeder.com> - update to 2.3.9.2 with security fixes: * CVE-2019-19722: Mails with group addresses in From or To fields caused crash in push notification drivers. * Mails with empty From/To headers can also cause crash in push notification drivers. ------------------------------------------------------------------- Wed Dec 4 21:46:28 UTC 2019 - Michael Ströder <michael@stroeder.com> - update to 2.3.9 and pigeonhole to 0.5.9 Dovecot 2.3.9 * Changed several event field names for consistency and to avoid conflicts in parent-child event relationships: * SMTP server command events: Renamed "name" to "cmd_name" * Events inheriting from a mailbox: Renamed "name" to "mailbox" * Server connection events have only "remote_ip", "remote_port", "local_ip" and "local_port". * Removed duplicate "client_ip", "ip" and "port". * Mail storage events: Removed "service" field. Use "service:<name>" category instead. * HTTP client connection events: Renamed "host" to "dest_host" and "port" to "dest_port" * auth: Drop Postfix socketmap support. It hasn't been working with recent Postfix versions for a while now. * push-notification-lua: The "subject" field is now decoded to UTF8 instead of kept as MIME-encoded. + push-notification-lua: Added new "from_address", "from_display_name", "to_address" and "to_display_name" fields. The display names are decoded to UTF8. + Added various new fields to existing events. See http://doc.dovecot.net/admin_manual/list_of_events.html + Add lmtp_add_received_header setting. It can be used to prevent LMTP from adding "Received:" headers. + doveadm: Support SSL/STARTTLS for proxied doveadm connections based on doveadm_ssl setting and proxy ssl/tls settings. + Log filters support now "service:<name>", which matches all events for the given service. It can also be used as a category. + lib: Use libunwind to get abort backtraces with function names where available. + lmtp: When the LMTP proxy changes the username (from passdb lookup) add an appropriate ORCPT parameter. - lmtp: Add lmtp_client_workarounds setting to implement workarounds for clients that send MAIL and RCPT commands with additional spaces before the path and for clients that omit <> brackets around the path. See example-config/conf.d/20-lmtp.conf. - lda/lmtp: Invalid MAIL FROM addresses were rejcted too aggressively. Now mails from addresses with unicode characters are delivered, but their Return-Path header will be <> instead of the given MAIL FROM address. - lmtp: The lmtp_hdr_delivery_address setting is ignored. - imap: imap_command_finished event's "args" and "human_args" parameters were always empty. - mbox: Seeking in zlib and bzip2 compressed input streams didn't work correctly. - imap-hibernate: Process crashed when client got destroyed while it was attempted to be unhibernated, and the unhibernation fails. - *-login: Proxying may have crashed if SSL handshake to the backend failed immediately. This was unlikely to happen in normal operation. - *-login: If TLS handshake to upstream server failed during proxying, login process could crash due to invalid memory access. - *-login: v2.3 regression: Using SASL authentication without initial response may have caused SSL connections to hang. This happened often at least with PHP's IMAP library. - *-login: When login processes are flooded with authentication attempts it starts logging errors about "Authentication server sent unknown id". This is still expected. However, it also caused the login process to disconnect from auth server and potentially log some user's password in the error message. - dict-sql: SQL prepared statements were not shared between sessions. This resulted in creating a lot of prepared statements, which was especially inefficient when using Cassandra backend with a lot of Cassandra nodes. - auth: auth_request_finished event didn't have success=yes parameter set for successful authentications. - auth: userdb dict - Trying to list users crashed. - submission: Service could be configured to allow anonymous authentication mechanism and anonymous user access. - LAYOUT=index: Corrupted dovecot.list.index caused folder creation to panic. - doveadm: HTTP server crashes if request target starts with double "/". - dsync: Remote dsync started hanging if the initial doveadm "dsync-server" command was sent in the same TCP packet as the following dsync handshake. v2.3.8 regression. - lib: Several "input streams" had a bug that in some rare situations might cause it to access freed memory. This could lead to crashes or corruption. The only currently known effect of this is that using zlib plugin with external mail attachments (mail_attachment_dir) could cause fetching the mail to return a few bytes of garbage data at the beginning of the header. Note that the mail wasn't saved corrupted, but fetching it caused corrupted mail to be sent to the client. - lib-storage: If a mail only has quoted content, use the quoted text for generating message snippet (IMAP PREVIEW) instead of returning empty snippet. - lib-storage: When vsize header was rebuilt, newly calculated message sizes were added to dovecot.index.cache instead of being directly saved into vsize records in dovecot.index. - lib: JSON generator was escaping UTF-8 characters unnecessarily. Pigeonhole 0.5.8 + Added events for Sieve and ManageSieve, see https://doc.dovecot.org/admin_manual/list_of_events/#pigeonhole + Pigeonhole: Implement the Sieve "special-use" extension described in RFC 8579. - duplicate: Test only compared the handles which would cause different values to be cached as the same duplicate test. Fix to also compare the actual hashes. - imap_sieve_filter: IMAP FILTER Command had various bugs in error handling. Errors may have been duplicated for each email, errors may have been missing entirely, command tag and ERRORS/WARNINGS parameters were swapped. ------------------------------------------------------------------- Fri Nov 8 12:20:14 UTC 2019 - Arjen de Korte <suse+build@de-korte.org> - Disable Link Time Optimization (LTO) (boo#1156301) ------------------------------------------------------------------- Tue Oct 8 17:31:00 UTC 2019 - Michael Ströder <michael@stroeder.com> - update to 2.3.8 and pigeonhole to 0.5.8 Dovecot 2.3.8 + Added mail_delivery_started and mail_delivery_finished events, see https://doc.dovecot.org/admin_manual/list_of_events/ for details. + dsync-replication: Don't replicate users who have "noreplicate" extra field in userdb. + doveadm service status: Show total number of processes created. + When logging to syslog, use instance_name setting's value for the ident. This commonly is added as a log prefix. + Base64 encoding/decoding code was rewritten with additional features. It shouldn't cause any user visible changes. - v2.3.7 regression: If a folder only receives new mails without any other mail access, dovecot.index.log keeps growing forever and dovecot.index keeps being rewritten for every mail delivery. - dsync-replication may lose keywords after syncing mails restored from another replica. This only happened if the mail only had keywords and no system flags. - event filters: Non-textual event fields could not be filtered using wildcards. - auth: Scope parameter was missing from OAuth password grant request. - doveadm client-server communication may hang in some situations. It is also using unnecessarily small TCP/IP packet sizes. - doveadm who and kick did not flush protocol output correctly. - imap: SETMETADATA with literal value would delete the metadata value instead of updating it. - imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the caching decisions should be updated so that newly saved mails will have the preview cached. - With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid permission bits in some files may have become dropped with some NFS servers. Changed NFS flushing to now use chmod() instead of chown(). - quota: warnings did not work if quota root was noenforcing - acl: Global ACL file ignored the last line if it didn't end with LF. - doveadm stats dump: With JSON formatter output numbers using the number type instead of as strings - lmtp_proxy: Ensure that real_* variables are correctly set when using lmtp_proxy. - event exporter: http-post driver had hardcoded timeout and did not support DNS lookups or TLS connections. - auth: Fix user iteration to work with userdb passwd with glibc v2.28. - auth: auth service can crash if auth-policy JSON response is invalid or returned too fast. - In some rare situations "ps" output could have shown a lot of "?" characters after Dovecot process titles. - When dovecot.index.pvt is empty, an unnecessary error is logged: Error: .../dovecot.index.pvt reset, view is now inconsistent - SMTP address encoder duplicated initial double quote character when the localpart of an address ended in '..'. For example "user+..@example.com" became ""user+.."@example.com in a sieve redirect. Pigeonhole 0.5.8 - Sieve may leak resources in rare cases when a redirect, vacation or report action fails to send the message. This mainly applies when Sieve is executed in IMAP context; i.e., for the IMAPSIEVE or FILTER=SIEVE capabilities. ------------------------------------------------------------------- Wed Aug 28 16:57:12 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.7.2 * CVE-2019-11500: IMAP protocol parser does not properly handle NUL byte when scanning data in quoted strings, leading to out of bounds heap memory writes. Found by Nick Roessler and Rafi Rubin. (boo#1145559) - update pigeonhole to 0.5.7.2 * CVE-2019-11500: ManageSieve protocol parser does not properly handle NUL byte when scanning data in quoted strings, leading to out of bounds heap memory writes. Found by Nick Roessler and Rafi Rubin. (boo#1145559) - refreshed patches to apply cleanly again: dovecot-2.3.0-better_ssl_defaults.patch dovecot-2.3.0-dont_use_etc_ssl_certs.patch ------------------------------------------------------------------- Tue Jul 23 20:06:59 UTC 2019 - Michael Ströder <michael@stroeder.com> - update to 2.3.7.1 and pigeonhole to 0.5.7.1 Dovecot 2.3.7.1 - Fix TCP_NODELAY errors being logged on non-Linux OSes - lmtp proxy: Fix assert-crash when client uses BODY=8BITMIME - Remove wrongly added checks in namespace prefix checking Pigeonhole 0.5.7.1 - dsync: Sieve script syncing failed if mailbox attributes weren't enabled. Dovecot 2.3.7 * fts-solr: Removed break-imap-search parameter + Added more events for the new statistics, see https://doc.dovecot.org/admin_manual/list_of_events/ + mail-lua: Add IMAP metadata accessors, see https://doc.dovecot.org/admin_manual/lua/ + Add event exporters that allow exporting raw events to log files and external systems, see https://doc.dovecot.org/configuration_manual/event_export/ + SNIPPET is now PREVIEW and size has been increased to 200 characters. + Add body option to fts_enforced. This triggers building FTS index only on body search, and an error using FTS index fails the search rather than reads through all the mails. - Submission/LMTP: Fixed crash when domain argument is invalid in a second EHLO/LHLO command. - Copying/moving mails using Maildir format loses IMAP keywords in the destination if the mail also has no system flags. - mail_attachment_detection_options=add-flags-on-save caused email body to be unnecessarily opened when FETCHing mail headers that were already cached. - mail attachment detection keywords not saved with maildir. - dovecot.index.cache may have grown excessively large in some situations. This happened especially when using autoexpunging with lazy_expunge folders. Also with mdbox format in general the cache file wasn't recreated as often as it should have. - Autoexpunged mails weren't immediately deleted from the disk. Instead, the deletion from disk happened the next time the folder was opened. This could have caused unnecessary delays if the opening was done by an interactive IMAP session. - Dovecot's TCP connections sometimes add extra 40ms latency due to not enabling TCP_NODELAY. HTTP and SMTP/LMTP connections weren't affected, but everything else was. This delay wasn't always visible - only in some situations with some message/packet sizes. - imapc: Fix various crash conditions - Dovecot builds were not always reproducible. - login-proxy: With shutdown_clients=no after config reload the existing connections could no longer be listed or kicked with doveadm. - "doveadm proxy kick" with -f parameter caused a crash in some situations. - Auth policy can cause segmentation fault crash during auth process shutdown if all auth requests have not been finished. - Fix various minor bugs leading into incorrect behaviour in mailbox list index handling. These rarely caused noticeable problems. - LDAP auth: Iteration accesses freed memory, possibly crashing auth-worker - local_name { .. } filter in dovecot.conf does not correctly support multiple names and wildcards were matched incorrectly. - replicator: dsync assert-crashes if it can't connect to remote TCP server. - config: Memory leak in config process when ssl_dh setting wasn't set and there was no ssl-parameters.dat file. This caused config process to die once in a while with "out of memory". ------------------------------------------------------------------- Mon May 20 14:25:49 UTC 2019 - Peter Varkoly <varkoly@suse.com> - bsc#1134242 - upgrade from 42.3 to 15.1: dovecot shows Unknown protocol 'SSLv2' * remove !SSLv2 from existing ssl_protocols configuration during upgrade ------------------------------------------------------------------- Tue Apr 30 13:49:18 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - update pigeonhole to 0.5.6 + sieve: Redirect loop prevention is sometimes ineffective. Improve existing loop detection by also recognizing the X-Sieve-Redirected-From header in incoming messages and dropping redirect actions when it points to the sending account. This header is already added by the redirect action, so this improvement only adds an additional use of this header. - sieve: Prevent execution of implicit keep upon temporary failure occurring at runtime. ------------------------------------------------------------------- Tue Apr 30 13:34:16 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.6: (boo#1133624 boo#1133625) * CVE-2019-11494: Submission-login crashed with signal 11 due to null pointer access when authentication was aborted by disconnecting. * CVE-2019-11499: Submission-login crashed when authentication was started over TLS secured channel and invalid authentication message was sent. * auth: Support password grant with passdb oauth2. + Use system default CAs for outbound TLS connections. + Simplify array handling with new helper macros. + fts_solr: Enable configuring batch_size and soft_commit features. - lmtp/submission: Fixed various bugs in XCLIENT handling, including a hang when XCLIENT commands were sent infinitely to the remote server. - lmtp/submission: Forwarded multi-line replies were erroneously sent as two replies to the client. - lib-smtp: client: Message was not guaranteed to contain CRLF consistently when CHUNKING was used. - fts_solr: Plugin was no longer compatible with Solr 7. - Make it possible to disable certificate checking without setting ssl_client_ca_* settings. - pop3c: SSL support was broken. - mysql: Closing connection twice lead to crash on some systems. - auth: Multiple oauth2 passdbs crashed auth process on deinit. - HTTP client connection errors infrequently triggered a segmentation fault when the connection was idle and not used for a particular client instance. - drop https://github.com/dovecot/core/commit/3c5101ffd.patch ------------------------------------------------------------------- Mon Apr 29 22:11:53 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - backport https://github.com/dovecot/core/commit/3c5101ffd.patch [PATCH] driver-mysql: Avoid double-closing MySQL connection ------------------------------------------------------------------- Thu Apr 18 11:40:06 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.5.2 (boo#1132501) * CVE-2019-10691: Trying to login with 8bit username containing invalid UTF8 input causes auth process to crash if auth policy is enabled. This could be used rather easily to cause a DoS. Similar crash also happens during mail delivery when using invalid UTF8 in From or Subject header when OX push notification driver is used. ------------------------------------------------------------------- Thu Mar 28 12:36:55 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.5.1 (boo#1130116) * CVE-2019-7524: Missing input buffer size validation leads into arbitrary buffer overflow when reading fts or pop3 uidl header from Dovecot index. Exploiting this requires direct write access to the index files. ------------------------------------------------------------------- Fri Mar 8 18:09:00 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.5 + Lua push notification driver: mail keywords and flags are provided in MessageNew and MessageAppend events. + submission: Implement support for plugins. + auth: When auth_policy_log_only=yes, only log what the policy server response would do without actually doing it. + auth: Always log policy server decisions with auth_verbose=yes - v2.3.[34]: doveadm log errors: Output was missing user/session - lda: Debug log lines could have shown slightly corrupted - login proxy: Login processes may have crashed in various ways when login_proxy_max_disconnect_delay was set. - imap: Fix crash with Maildir+zlib if client disconnects during APPEND - lmtp proxy: Fix potential assert-crash - lmtp/submission: Fix crash when SMTP client transaction times out - submission: Split large XCLIENT commands to 512 bytes per command, so Postfix accepts them. - submission: Fix crash when client sends invalid BURL command - submission: relay backend: VRFY command: Avoid forwarding 500 and 502 replies back to client. - lib-http: Fix potential assert-crash when DNS lookup fails - lib-fts: Fix search query generation when one language ignores a token (e.g. via stopwords). - update pigeonhole to 0.5.5 + IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting which causes messages discarded by an IMAPSieve script to be expunged immediately, rather than only being marked as "\Deleted" (which is still the default behavior). - IMAPSieve: Fix panic crash occurring when a COPY command copies messages from a virtual mailbox where the source messages originate from more than a single real mailbox. - imap4flags extension: Fix deleting all keywords. When the action resulted in all keywords being removed, no changes were actually applied. - variables extension: Fix truncation of UTF-8 variable content. The maximum size of Sieve variables was enforced by truncating the variable string content bluntly at the limit, but this does not consider UTF-8 code point boundaries. This resulted in broken UTF-8 strings. This problem also surfaced for variable modifiers, such as the ":encodeurl" modifier provided by the Sieve "enotify" extension. In that case, the resulting URI escaping could also be truncated inappropriately. - IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message. Sieve scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context that modify the message, stored the message a second time, rather than replacing the originally stored unmodified message. - Fix segmentation fault occurring when both the sieve_extprograms plugin (for the Sieve interpreter) and the imap_filter_sieve plugin (for IMAP) are loaded at the same time. A symbol was defined by both plugins, causing a clash when both were loaded. - drop patches which were backports - 10048229...de42b54a.patch - 3c5101ffdd2a8115e03ed7180d53578765dea4c9.patch ------------------------------------------------------------------- Tue Feb 5 13:45:52 UTC 2019 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.4.1 (boo#1123022) * CVE-2019-3814: If imap/pop3/managesieve/submission client has trusted certificate with missing username field (ssl_cert_username_field), under some configurations Dovecot mistakenly trusts the username provided via authentication instead of failing. * ssl_cert_username_field setting was ignored with external SMTP AUTH, because none of the MTAs (Postfix, Exim) currently send the cert_username field. This may have allowed users with trusted certificate to specify any username in the authentication. This bug didn't affect Dovecot's Submission service. ------------------------------------------------------------------- Thu Jan 17 21:57:42 UTC 2019 - Arjen de Korte <suse+build@de-korte.org> - add buildrequires zlib-devel which used to be pulled in by other buildrequires, but no longer is ------------------------------------------------------------------- Thu Dec 6 17:32:43 UTC 2018 - Marcus Rueckert <mrueckert@suse.de> - added 3c5101ffdd2a8115e03ed7180d53578765dea4c9.patch: fix crash with mysql/mariadb ------------------------------------------------------------------- Sun Nov 25 00:17:08 UTC 2018 - Marcus Rueckert <mrueckert@suse.de> - added 10048229...de42b54a.patch: Fix build failures on TW i586 ------------------------------------------------------------------- Sat Nov 24 00:27:59 UTC 2018 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.4 * The default postmaster_address is now "postmaster@<user domain or server hostname>". If username contains the @domain part, that's used. If not, then the server's hostname is used. * "doveadm stats dump" now returns two decimals for the "avg" field. + Added push notification driver that uses a Lua script + Added new SQL, DNS and connection events. See https://wiki2.dovecot.org/Events + Added "doveadm mailbox cache purge" command. + Added events API support for Lua scripts + doveadm force-resync -f parameter performs "index fsck" while opening the index. This may be useful to fix some types of broken index files. This may become the default behavior in a later version. - director: Kicking a user crashes if login process is very slow - pop3_no_flag_updates=no: Don't expunge DELEted and RETRed messages unless QUIT is sent. - auth: Fix crypt() segfault with glibc-2.28+ - imap: Running UID FILTER script with errors assert-crashes - dsync, pop3-migration: POP3 UIDLs weren't added to dovecot.index.cache while mails were saved. - dict clients may have been using 100% CPU while waiting for dict server to finish commands. - doveadm user: Fixed user listing via HTTP API - All levels of Cassandra log messages were logged as Dovecot errors. - http/smtp client may have crashed after SSL handshake - Lua auth converted strings that looked like numbers into numbers. - update pigeonhole to 0.5.4 * Adjustments to several changes in Dovecot v2.3.4 make this Pigeonhole release dependent on that Dovecot release; it will not compile against older Dovecot versions. And, conversely, you need to upgrade Pigeonhole when upgrading Dovecot to v2.3.4. * The changes regarding the default postmaster_address in Dovecot v2.3.4 mainly apply to Pigeonhole. The new default should work for all existing installations, thereby fixing several reported v2.3/v0.5 migration problems. - IMAP FILTER=SIEVE capability: Fix assert crash occurring when running UID FILTER on a Sieve script with errors. ------------------------------------------------------------------- Mon Oct 1 22:55:38 UTC 2018 - Marcus Rueckert <mrueckert@suse.de> - update pigeonhole to 0.5.3 - Fix assertion panic occurring when managesieve service fails to open INBOX while saving a Sieve script. This was caused by a lack of cleanup after failure. - Fix specific messages causing an assert panic with actions that compose a reply (e.g. vacation). With some rather weird input from the original message, the header folding algorithm (as used for composing the References header for the reply) got confused, causing the panic. - IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing. After finishing reading the Sieve script, the command parsing sometimes didn't continue with the search arguments. This is a time- critical bug that likely only occurs when the Sieve script is sent in the next TCP frame. ------------------------------------------------------------------- Mon Oct 1 22:54:12 UTC 2018 - Marcus Rueckert <mrueckert@suse.de> - update to 2.3.3 * doveconf hides more secrets now in the default output. * ssl_dh setting is no longer enforced at startup. If it's not set and non-ECC DH key exchange happens, error is logged and client is disconnected. + Added log_debug=<filter> setting. + Added log_core_filter=<log filter> setting. + quota-clone: Write to dict asynchronously + --enable-hardening attempts to use retpoline Spectre 2 mitigations + lmtp proxy: Support source_ip passdb extra field. + doveadm stats dump: Support more fields and output stddev by default. + push-notification: Add SSL support for OX backend. - NUL bytes in mail headers can cause truncated replies when fetched. - director: Conflicting host up/down state changes may in some rare situations ended up in a loop of two directors constantly overwriting each others' changes. - director: Fix hang/crash when multiple doveadm commands are being handled concurrently. - director: Fix assert-crash if doveadm disconnects too early - virtual plugin: Some searches used 100% CPU for many seconds - dsync assert-crashed with acl plugin in some situations. - mail_attachment_detection_options=add-flags-on-save assert-crashed with some specific Sieve scripts. - Mail snippet generation crashed with mails containing invalid Content-Type:multipart header. - Log prefix ordering was different for some log lines. - quota: With noenforcing option current quota usage wasn't updated. - auth: Kerberos authentication against Samba assert-crashed. - stats clients were unnecessarily chatty with the stats server. - imapc: Fixed various assert-crashes when reconnecting to server. - lmtp, submission: Fix potential crash if client disconnects while handling a command. - quota: Fixed compiling with glibc-2.26 / support libtirpc. - fts-solr: Empty search values resulted in 400 Bad Request errors - fts-solr: default_ns parameter couldn't be used - submission server crashed if relay server returned over 7 lines in a reply (e.g. to EHLO) - dropped 4ff4bd024a9b6e7973b76b186ce085c2ca669d3e.patch: included in update ------------------------------------------------------------------- Fri Jul 13 21:23:16 UTC 2018 - mrueckert@suse.de - added https://github.com/dovecot/core/commit/4ff4bd024a9b6e7973b76b186ce085c2ca669d3e.patch ------------------------------------------------------------------- Wed Jul 11 14:17:57 UTC 2018 - mrueckert@suse.de - update to 2.3.2.1 - SSL/TLS servers may have crashed during client disconnection - lmtp: With lmtp_rcpt_check_quota=yes mail deliveries may have sometimes assert-crashed. - v2.3.2: "make check" may have crashed with 32bit systems ------------------------------------------------------------------- Sat Jun 30 20:06:40 UTC 2018 - mrueckert@suse.de - update to 2.3.2 * old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root. + doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details. + doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details. + cassandra: Use fallback_consistency on more types of errors + lmtp proxy: Support outgoing SSL/TLS connections + lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings. + submission: Add support for rawlog_dir + submission: Add submission_client_workarounds setting. + lua auth: Add password_verify() function and additional fields in auth request. - doveadm-server: TCP connections are hanging when there is a lot of network output. This especially caused hangs in dsync-replication. - Using multiple type=shared mdbox namespaces crashed - mail_fsync setting was ignored. It was always set to "optimized". - lua auth: Fix potential crash at deinit - SSL/TLS servers may have crashed if client disconnected during handshake. - SSL/TLS servers: Don't send extraneous certificates to client when alt certs are used. - lda, lmtp: Return-Path header without '<' may have assert-crashed. - lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash - lda: -f parameter didn't allow empty/null/domainless address - lmtp, submission: Message size limit was hardcoded to 40 MB. Exceeding it caused the connection to get dropped during transfer. - lmtp: Fix potential crash when delivery fails at DATA stage - lmtp: login_greeting setting was ignored - Fix to work with OpenSSL v1.0.2f - systemd unit restrictions were too strict by default - Fix potential crashes when a lot of log output was produced - SMTP client may have assert-crashed when sending mail - IMAP COMPRESS: Send "end of compression" marker when disconnecting. - cassandra: Fix consistency=quorum to work - dsync: Lock file generation failed if home directory didn't exist - Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets. - imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone. - pop3c: Handle unexpected server disconnections without assert-crash - fts: Fixes to indexing mails via virtual mailboxes. - fts: If mails contained NUL characters, the text around it wasn't indexed. - Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it. - update pigeonhole to 0.5.2 + Implement plugin for the a vendor-defined IMAP capability called "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering in IMAP. More information can be found in doc/plugins/imap_filter_sieve.txt. - The Sieve addess test caused an assertion panic for invalid addresses with UTF-8 codepoints in the localpart. Fixed by properly detecting invalid addresses with UTF-8 codepoints in the localpart and skipping these like other invalid addresses while iterating addresses for the address test. - Make the length of the subject header for the vacation response configurable and enforce the limit in UTF-8 codepoints rather than bytes. The subject header for a vacation response was statically truncated to 256 bytes, which is too limited for multi-byte UTF-8 characters. - Sieve editheader extension: Fix assertion panic occurring when it is used to manipulate a message header with a very large header field. - Properly abort execution of the sieve_discard script upon error. Before, the LDA Sieve plugin attempted to execute the sieve_discard script when an error occurs. This can lead to the message being lost. - Fix the interaction between quota and the sieve_discard script. When quota was used together with a sieve_discard script, the message delivery did not bounce when the quota was exceeded. - refreshed to apply cleanly again dovecot-2.3.0-better_ssl_defaults.patch - dropped patches: - 35497604d80090a02619024aeec069b32568e4b4.diff - 5522b8b3d3ed1a99c3b63bb120216af0bd427403.diff - 847790d5aab84df38256a6f9b4849af0eb408419.patch ------------------------------------------------------------------- Sun May 27 09:31:02 UTC 2018 - mrueckert@suse.de - added 847790d5aab84df38256a6f9b4849af0eb408419.patch: Fix crash for over quota users ------------------------------------------------------------------- Thu May 24 09:42:48 UTC 2018 - kbabioch@suse.com - Use OpenPGP signatures provided upstream - Added dovecot23.keyring, which contains the keys from the upstream projects ------------------------------------------------------------------- Tue Apr 10 15:46:04 UTC 2018 - varkoly@suse.com - bnc#1088911 - dovecot23 can not build ond s390 add: 35497604d80090a02619024aeec069b32568e4b4.diff add: 5522b8b3d3ed1a99c3b63bb120216af0bd427403.diff ------------------------------------------------------------------- Wed Mar 28 09:02:33 UTC 2018 - mrueckert@suse.de - update pigeonhole to 0.5.1 - Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve script. - editheader extension: Corrected the stream position calculations performed while making the modified message available as a stream. Pigeonhole Sieve crashed in LMTP with an assertion panic when the Sieve editheader extension was used before the message was redirected. Experiments indicate that the problem occurred only with LMTP and that LDA is not affected. - fileinto extension: Fix assert panic occurring when fileinto is used without being listed in the require line, while the copy extension is listed there. This is a very old bug. - imapsieve plugin: Do not assert crash or log an error for messages that disappear concurrently while applying Sieve scripts. This event is now logged as a debug message. - Sieve extprograms plugin: Large output from "execute" command crashed delivery. Fixed buffering issue in code that handles output from the external program. ------------------------------------------------------------------- Tue Mar 27 18:28:48 UTC 2018 - mrueckert@suse.de - update to 2.3.1 * Submission server support improvements and bug fixes - Lots of bug fixes to submission server * API CHANGE: array_idx_modifiable will no longer allocate space - Particularly affects how you should check MODULE_CONTEXT result, or use REQUIRE_MODULE_CONTEXT. + mail_attachment_detection_options setting controls when $HasAttachment and $HasNoAttachment keywords are set for mails. + imap: Support fetching body snippets using FETCH (SNIPPET) or (SNIPPET (LAZY=FUZZY)) + fs-compress: Automatically detect whether input is compressed or not. Prefix the compression algorithm with "maybe-" to enable the detection, for example: "compress:maybe-gz:6:..." + Added settings to change dovecot.index* files' optimization behavior. See https://wiki2.dovecot.org/IndexFiles#Settings + Auth cache can now utilize auth workers to do password hash verification by setting auth_cache_verify_password_with_worker=yes. + Added charset_alias plugin. See https://wiki2.dovecot.org/Plugins/CharsetAlias + imap_logout_format and pop3_logout_format settings now support all of the generic variables (e.g. %{rip}, %{session}, etc.) + Added auth_policy_check_before_auth, auth_policy_check_after_auth and auth_policy_report_after_auth settings. + master: Support HAProxy PP2_TYPE_SSL command and set "secured" variable appropriately - Invalid UCS4 escape in HTML can cause crashes - imap: IMAP COMPRESS -enabled client crashes on disconnect - lmtp: Fix crash when user is over quota - lib-lda: Parsing Return-Path header address fails when it contains CFWS - auth: SASL with Exim fails for AUTH commands without an initial response - imap: SPECIAL-USE capability isn't automatically added - auth: LDAP subqueries do not support standard auth variables in var-expand - auth: SHA256-CRYPT and SHA512-CRYPT schemes do not work - lib-index: mail_always/never_cache_fields are not used for existing cache files - imap: Fetching headers leaks memory if search doesn't find any mails - lmtp: ORCPT support in RCPT TO - imap-login: Process sometimes ends up in infinite loop - sdbox: Rolled back save/copy transaction doesn't delete temp files - mail: lock_method=dotlock causes crashes - drop patches which are included in the update 23da0fa1b30cc11bcc1d467674a0950c527e9ff1.patch dovecot-2.3.0.1-over-quota-lmtp-crash.patch ------------------------------------------------------------------- Tue Mar 13 10:40:48 UTC 2018 - dimstar@opensuse.org - Fix License tag. ------------------------------------------------------------------- Wed Mar 7 12:25:51 UTC 2018 - mrueckert@suse.de - added 23da0fa1b30cc11bcc1d467674a0950c527e9ff1.patch ------------------------------------------------------------------- Wed Mar 7 12:10:44 UTC 2018 - mrueckert@suse.de - update license to SPDX-3 ------------------------------------------------------------------- Tue Mar 6 19:28:49 UTC 2018 - mrueckert@suse.de - update pigeonhole to 0.5.0.1 - imap4flags extension: Fix binary corruption occurring when setflag/addflag/removeflag flag-list is a variable. - sieve-extprograms plugin: Fix segfault occurring when used in IMAPSieve context. - drop 321a39be974deb2e7eff7b2a509a3ee6ff2e5ae1.patch ------------------------------------------------------------------- Tue Mar 6 17:54:58 UTC 2018 - mrueckert@suse.de - pull backport patch dovecot-2.3.0.1-over-quota-lmtp-crash.patch ------------------------------------------------------------------- Tue Mar 6 13:48:50 UTC 2018 - mrueckert@suse.de - update to 2.3.0.1 * CVE-2017-15130: TLS SNI config lookups may lead to excessive memory usage, causing imap-login/pop3-login VSZ limit to be reached and the process restarted. This happens only if Dovecot config has local_name { } or local { } configuration blocks and attacker uses randomly generated SNI servernames. (boo#1082828) * CVE-2017-14461: Parsing invalid email addresses may cause a crash or leak memory contents to attacker. For example, these memory contents might contain parts of an email from another user if the same imap process is reused for multiple users. First discovered by Aleksandar Nikolic of Cisco Talos. Independently also discovered by "flxflndy" via HackerOne. (boo#1082826) * CVE-2017-15132: Aborted SASL authentication leaks memory in login process. (boo#1075608) * Linux: Core dumping is no longer enabled by default via PR_SET_DUMPABLE, because this may allow attackers to bypass chroot/group restrictions. Found by cPanel Security Team. Nowadays core dumps can be safely enabled by using "sysctl -w fs.suid_dumpable=2".

(boo#1070871) ------------------------------------------------------------------- Wed Dec 20 10:32:23 UTC 2017 - mrueckert@suse.de - starting 2.3 package based on the latest 2.2 branch There are several new and exciting features in v2.3.0. I'm especially happy about the new logging and statistics code, which will allow us to generate statistics for just about everything. We didn't have time to implement everything we wanted for them yet, and there especially aren't all that many logging events yet that can be used for statistics. We'll implement those to v2.3.1, which might also mean that some of the APIs might still change in v2.3.1 if that's required. We also have new lib-smtp server code, which was used to implement SMTP submission server and do a partial rewrite for LMTP server. Some of the larger changes: * Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3 If you upgrade from 2.2: Config file changes: - Removed: /etc/dovecot/conf.d/11-object-storage.conf - Added: /etc/dovecot/conf.d/20-submission.conf * Logging rewrite started: Logging is now based on hierarchical events. This makes it possible to do various things, like: 1) giving consistent log prefixes, 2) enabling debug logging with finer granularity, 3) provide logs in more machine readable formats (e.g. json). Everything isn't finished yet, especially a lot of the old logging code still needs to be translated to the new way. * Statistics rewrite started: Stats are now based on (log) events. It's possible to gather statistics about any event that is logged. See http://wiki2.dovecot.org/Statistics for details * ssl_dh setting replaces the old generated ssl-parameters.dat * IMAP: When BINARY FETCH finds a broken mails, send [PARSE] error instead of [UNKNOWNCTE] * Linux: core dumping via PR_SET_DUMPABLE is no longer enabled by default due to potential security reasons (found by cPanel Security Team). + Added support for SMTP submission proxy server, which includes support for BURL and CHUNKING extension. + LMTP rewrite. Supports now CHUNKING extension and mixing of local/proxy recipients. + auth: Support libsodium to add support for ARGON2I and ARGON2ID password schemes. + auth: Support BLF-CRYPT password scheme in all platforms + auth: Added LUA scripting support for passdb/userdb. See https://wiki2.dovecot.org/AuthDatabase/Lua - Input streams are more reliable now when there are errors or when the maximum buffer size is reached. Previously in some situations this could have caused Dovecot to try to read already freed memory. - Output streams weren't previously handling failures when writing a trailer at the end of the stream. This mainly affected encrypt and zlib compress ostreams, which have silently written truncated files if the last write happened to fail (which shouldn't normally have ever happened). - virtual plugin: Fixed panic when fetching mails from virtual mailboxes with IMAP BINARY extension. - doveadm-server: Fix potential hangs with SSL connections - doveadm proxy: Reading commands' output from v2.2.33+ servers could have caused the output to be corrupted or caused a crash. - Many other smaller fixes - patches: - dovecot-2.3.0-better_ssl_defaults.patch - dovecot-2.3.0-dont_use_etc_ssl_certs.patch
