Slackware alert: Security updates: at, sudo, xchat

New packages are now available to address security issues with the at
scheduler program (found in Slackware 8.0's bin.tgz package), sudo, and
xchat.

Here's the information from the Slackware 8.0 ChangeLog:

Mon Jan 21 13:21:07 PST 2002
patches/packages/at.tgz:  Fixed a buffer overflow.
(* Security fix *)
patches/packages/sudo.tgz:  Upgraded to sudo-1.6.5p1.
  This fixes a vulnerability where the mail system could be exploited.  So far,
  the only working examples of this problem require Postfix to be installed,
  but it's possible that exploits involving other mailers could emerge.
(* Security fix *)
patches/packages/xchat.tgz:  Upgraded to xchat-1.8.7.
  This fixes a problem where an attacker could execute IRC server commands as
  the user running xchat.
(* Security fix *)

We recommend upgrading these packages as soon as possible.
