1. Summary:

An updated metamail package that fixes a buffer overflow vulnerability for
Red Hat Enterprise Linux 2.1 is now available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

Metamail is a system for handling multimedia mail.

A buffer overflow bug was found in the way Metamail processes certain mail
messages. An attacker could create a carefully-crafted message such that
when it is opened by a victim and parsed through Metamail, it runs
arbitrary code as the victim. The Common Vulnerabilities and Exposures
project (cve.mitre.org) assigned the name CVE-2006-0709 to this issue.

Users of Metamail should upgrade to this updated package, which contains a
backported patch that is not vulnerable to this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
