1. Summary:

An updated gaim package that fixes security issues, fixes various bugs, and includes various enhancements for Red Hat Enterprise Linux 3 is now avaliable.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

The gaim application is a multi-protocol instant messaging client.

A buffer overflow has been discovered in the MSN protocol handler.  When receiving unexpected sequence of MSNSLP messages, it is possible that an attacker could cause an internal buffer overflow, leading to a crash or possible code execution.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0891 to this issue.

This updated gaim package also fixes multiple user interface, protocol, and error handling problems, including an ICQ communication encoding issue.

Additionally, these updated packages have compiled gaim as a PIE (position independent executable) for added protection against future security vulnerabilities.

All users of gaim should upgrade to this updated package, which includes various bug fixes, as well as a backported security patch.

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:

    up2date
