                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           xchat
Advisory ID:            MDKSA-2002:051
Date:                   August 14th, 2002
Affected versions:      7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1
________________________________________________________________________

Problem Description:

 In versions of the xchat IRC client prior to version 1.8.9, xchat does
 not filter the response from an IRC server when a /dns query is
 executed.  xchat resolves hostnames by passing the configured resolver
 and hostname to a shell, so an IRC server may return a malicious
 response formatted so that arbitrary commands are executed with the
 privilege of the user running xchat.

of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".  A list of
FTP mirrors can be obtained from:

  http://www.mandrakesecure.net/en/ftp.php

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:

  rpm --checksig <filename>

All packages are signed by MandrakeSoft for security.  You can obtain
the GPG public key of the Mandrake Linux Security Team from:

  https://www.mandrakesecure.net/RPM-GPG-KEYS

Please be aware that sometimes it takes the mirrors a few hours to 
update.
