> - Update sudo from 1.9.5p1 to 1.9.5p2
> - Major changes between version 1.9.5p2 and 1.9.5p1:
>     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.
>     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.
