3. Problem description:
X-Chat is a graphical IRC chat client for the X Window System.
A stack buffer overflow has been fixed in the SOCKSv5 proxy code.
An attacker could create a malicious SOCKSv5 proxy server in such a way
that X-Chat would execute arbitrary code if a victim configured X-Chat to
use the proxy. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0409 to this issue.
Users of X-Chat should upgrade to this erratum package, which contains a
backported security patch, and is not vulnerable to this issue.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:
