- clamav-document-maxsize.patch: in the "clamscan" and "clamdscan" manpages,
  document that files over a certain size by default will silently not be
  scanned and how this can be adjusted (bsc#1187509)
--------------------------------------------------------------------
- bsc#1192346: Update to 0.103.4
- bsc#1188284: Update to 0.103.3
  * obsoletes clamav-disable-timestamps.patch

- Update to 0.103.4
  * FreshClam:
    - Add a 24-hour cool-down for FreshClam clients that have received
      an HTTP 403 (Forbidden) response from the CDN. This is to reduce
      the volume of 403-response data served to blocked FreshClam
      clients that are configured with a tight update-loop.
    - Fixed a bug where FreshClam treats an empty CDIFF as an
      incremental update failure instead of as an intentional request
      to download the whole CVD.
  * ClamDScan: Fix a scan error when broken symlinks are encountered on
    macOS with "FollowDirectorySymlinks" and "FollowFileSymlinks"
    options disabled.
  * Overhauled the scan recursion / nested archive extraction logic and
    added new limits on embedded file-type recognition performed during
    the "raw" scan of each file. This limits embedded file-type
    misidentification and prevents detecting embedded file content that
    is found/extracted and scanned at other layers in the scanning
    process.
  * Fix an issue with the FMap module that failed to read from some
    nested files.
  * Fixed an issue where failing to load some rules from a Yara file
    containing multiple rules may cause a crash.
  * Fixed assorted compiler warnings.
  * Fixed assorted Coverity static code analysis issues.
  * Scan limits:
    - Added virus-name suffixes to the alerts that trigger when a scan
      limit has been exceeded. Rather than simply
      Heuristics.Limits.Exceeded, you may now see limit-specific
      virus-names, to include:
      + Heuristics.Limits.Exceeded.MaxFileSize

- Update to 0.103.3
  * Fixed a scan performance issue when ENGINE_OPTIONS_FORCE_TO_DISK is
    enabled. This issue did not impacted most users but for those
    affected it caused every scanned file to be copied to the temp
    directory before the scan.
  * Fix ClamDScan crashes when using the --fdpass --multiscan
    command-line options in combination with the ClamD ExcludePath
    config file options.
  * Fixed an issue where the mirrors.dat file is owned by root when
    starting as root (or with sudo) and using daemon-mode. File
    ownership will be set to the DatabaseOwner just before FreshClam
    switches to run as that user.
  * Renamed the mirrors.dat file to freshclam.dat.
  * Disabled the HTTPUserAgent config option if the DatabaseMirror uses
    clamav.net. This will prevent users from being inadvertently blocked
    and will ensure that we can keep better metrics on which ClamAV
    versions are being used.
  * Moved the detection for Heuristics.PNG.CVE-2010-1205 behind the
    ClamScan --alert-broken-media option (ClamD AlertBrokenMedia yes)
    option. This type of PNG issue appears to be common enough to be an
    annoyance, and the CVE is old enough that no one should be
    vulnerable at this point.
  * Fix ClamSubmit failures after changes to Cloudflare "__cfduid"
    cookies. See: https://blog.cloudflare.com/deprecating-cfduid-cookie/

    loop. Affects 0.103.0 and 0.103.1 only.
  * CVE-2021-1404, bsc#1184533: Fix for PDF parser buffer over-read;
    possible crash. Affects 0.103.0 and 0.103.1 only.

- Update to 0.103.2
  * CVE-2021-1386: Fix for UnRAR DLL load privilege escalation.
    Affects 0.103.1 and prior on Windows only.
  * CVE-2021-1252: Fix for Excel XLM parser infinite loop. Affects
    0.103.0 and 0.103.1 only.
  * CVE-2021-1404: Fix for PDF parser buffer over-read; possible
    crash. Affects 0.103.0 and 0.103.1 only.
  * CVE-2021-1405: Fix for mail parser NULL-dereference crash.
    Affects 0.103.1 and prior.
  * Fix possible memory leak in PNG parser.
  * Fix ClamOnAcc scan on file-creation race condition so files are
    scanned after their contents are written.
  * FreshClam: Deprecate the SafeBrowsing config option. The
    SafeBrowsing option will no longer do anything.
  * For more details, see our blog post from last year about the
    future of the ClamAV Safe Browsing database.
  * FreshClam: Improved HTTP 304, 403, & 429 handling.
  * FreshClam: Added back the mirrors.dat file to the database directory.
  * FreshClam will now exit with a failure in daemon mode if an HTTP 403
    (Forbidden) was received, because retrying later won't help any. The
    FreshClam user will have to take actions to get unblocked.
  * Fix the FreshClam mirror-sync issue where a downloaded database is
    "older than the version advertised."

baserev update by copy to link target

Reinhard Max (rmax) accepted request 869944 from

Arjen de Korte (adkorte) almost 4 years ago (revision 216)

- Update to 0.103.1
  * Added a new scan option to alert on broken media (graphics) file
    formats. This feature mitigates the risk of malformed media files
    intended to exploit vulnerabilities in other software. At present
    media validation exists for JPEG, TIFF, PNG, and GIF files. To
    enable this feature, set AlertBrokenMedia yes in clamd.conf, or
    use the --alert-broken-media option when using clamscan. These
    options are disabled by default in this patch release, but may be
    enabled in a subsequent release. Application developers may enable
    this scan option by enabling CL_SCAN_HEURISTIC_BROKEN_MEDIA for
    the heuristic scan option bit field.
  * Added CL_TYPE_TIFF, CL_TYPE_JPEG types to match GIF, PNG typing
    behavior. BMP and JPEG 2000 files will continue to detect as
    CL_TYPE_GRAPHICS because ClamAV does not yet have BMP or JPEG
    2000 format checking capabilities.
  * Fixed PNG parser logic bugs that caused an excess of parsing
    errors and fixed a stack exhaustion issue affecting some systems
    when scanning PNG files. PNG file type detection was disabled via
    signature database update for ClamAV version 0.103.0 to mitigate
    the effects from these bugs.
  * Fixed an issue where PNG and GIF files no longer work with
    Target:5 graphics signatures if detected as CL_TYPE_PNG/GIF rather
    than as CL_TYPE_GRAPHICS. Target types now support up to 10
    possible file types to make way for additional graphics types in
    future releases.
  * Fixed clamonacc's --fdpass option.
    - Interprocess file descriptor passing for clamonacc was broken
      since version 0.102.0 due to a bug introduced by the switch to
      curl for communicating with clamd. On Linux, passing file
      descriptors from one process to another is handled by the
      kernel, so we reverted clamonacc to use standard system calls
      for socket communication when fd passing is enabled.
  * Fixed a clamonacc stack corruption issue on some systems when
    using an older version of libcurl.
  * Allow clamscan and clamdscan scans to proceed even if the
    realpath lookup failed. This alleviates an issue on Windows
    scanning files hosted on file- systems that do not support the
    GetMappedFileNameW() API such as on ImDisk RAM-disks.
  * Fixed freshclam --on-update-execute=EXIT_1 temporary directory
    cleanup issue.
  * clamd's log output and VirusEvent now provide the scan target's
    file path instead of a file descriptor. The clamd socket API for
    submitting a scan by FD-passing doesn't include a file path, this
    feature works by looking up the file path by file descriptor.
    This feature works on Mac and Linux but is not yet implemented
    for other UNIX operating systems. FD-passing is not available for
    Windows.
  * Fixed an issue where freshclam database validation didn't work
    correctly when run in daemon mode on Linux/Unix.

- bsc#1119353, clamav-fips.patch: Fix freshclam crash in FIPS mode.
- Keep OBS from installing an existing clamav instance to scan the
  sources, because this makes "make check" use the old library
  instead of the just built one. This is only a workaround until
  we found a way to keep libtool from adding libdir to rpath and
  LD_LIBRARY_PATH of the binaries in the testsuite.

- Update to 0.103.0
  * clamd can now reload the signature database without blocking
    scanning. This multi-threaded database reload improvement was made
    possible thanks to a community effort.
    - Non-blocking database reloads are now the default behavior. Some
      systems that are more constrained on RAM may need to disable
      non-blocking reloads as it will temporarily consume two times as
      much memory. We added a new clamd config option
      ConcurrentDatabaseReload, which may be set to no.
  * Dropped clamav-str-h.patch (no longer needed)
  * Fix clamav-milter.service (requires clamd.service to run)

- Update to 0.102.4
  * CVE-2020-3350: Fix a vulnerability wherein a malicious user could
    replace a scan target's directory with a symlink to another path
    to trick clamscan, clamdscan, or clamonacc into removing or moving
    a different file (eg. a critical system file). The issue would
    affect users that use the --move or --remove options for clamscan,
    clamdscan, and clamonacc.
  * CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing
    module in ClamAV 0.102.3 that could cause a Denial-of-Service
    (DoS) condition. Improper bounds checking results in an
    out-of-bounds read which could cause a crash. The previous fix for
    this CVE in 0.102.3 was incomplete. This fix correctly resolves
    the issue.
  * CVE-2020-3481: Fix a vulnerability in the EGG archive module in
    ClamAV 0.102.0 - 0.102.3 could cause a Denial-of-Service (DoS)
    condition. Improper error handling may result in a crash due to a
    NULL pointer dereference. This vulnerability is mitigated for
    those using the official ClamAV signature databases because the
    file type signatures in daily.cvd will not enable the EGG archive
    parser in versions affected by the vulnerability.
