[slackware-security]  Mutt buffer overflow in IMAP support

The mutt mail client packages in Slackware 8.1 and 9.0 have been
upgraded to mutt-1.4.1i to fix a security problem discovered by
Core Security Technologies.  This issue may allow a remote
attacker controlling a malicious IMAP server to execute code on
your machine as the user running mutt if you connect to the IMAP
server using mutt.

All sites running mutt are advised to upgrade.

More information on the problem can be found here:

Here are the details from the Slackware 9.0 ChangeLog:
+--------------------------+
Sat Mar 29 13:46:36 PST 2003
patches/packages/mutt-1.4.1i-i386-1.tgz:  Upgraded to mutt-1.4.1i.
  From www.mutt.org:
    Mutt 1.4.1 and 1.5.4 were released on March 19, 2003. These
    releases both fix a buffer overflow identified by Core Security
    Technologies. The only differences between 1.4 and 1.4.1 are bug
    fixes. If you are currently using 1.4, it's probably a very good
    idea to update.
  (* Security fix *)
