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:
