- Update to 1.9.5.p2
* When invoked as sudoedit, the same set of command line
options are now accepted as for sudo -e. The -H and -P
options are now rejected for sudoedit and sudo -e which
matches the sudo 1.7 behavior. This is part of the fix for
CVE-2021-3156.
* Fixed a potential buffer overflow when unescaping backslashes
in the command's arguments. Normally, sudo escapes special
characters when running a command via a shell (sudo -s or
sudo -i). However, it was also possible to run sudoedit with
the -s or -i flags in which case no escaping had actually
been done, making a buffer overflow possible.
This fixes CVE-2021-3156. (bsc#1181090)
* Fixed sudo's setprogname(3) emulation on systems that don't
provide it.
* Fixed a problem with the sudoers log server client where a
partial write to the server could result the sudo process
consuming large amounts of CPU time due to a cycle in the
buffer queue. Bug #954.
* Added a missing dependency on libsudo_util in libsudo_eventlog.
Fixes a link error when building sudo statically.
* The user's KRB5CCNAME environment variable is now preserved
when performing PAM authentication. This fixes GSSAPI
authentication when the user has a non-default ccache. (forwarded request 867021 from simotek)
