[slackware-security]  sudo (SSA:2021-026-01)

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.
  For more information, see:

  (* Security fix *)
