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.

If you want to upgrade manually, download the updated package from one
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.
