[slackware-security] sudo

New sudo packages are available for Slackware 14.0, 14.1, 14.2, and -current to
fix security issues.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/sudo-1.9.5p2-i586-1_slack14.2.txz: Upgraded.
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.
