"Updated XFree86 packages that fix several security issues in libXpm,
as well as other bug fixes, are now available for Red Hat Enterprise
Linux 2.1.

XFree86 is an open source implementation of the X Window System. It
provides the basic low level functionality which full fledged
graphical user interfaces (GUIs) such as GNOME and KDE are designed
upon.

During a source code audit, Chris Evans discovered several stack
overflow flaws and an integer overflow flaw in the X.Org libXpm
library used to decode XPM (X PixMap) images. An attacker could create
a carefully crafted XPM file which would cause an application to crash
or potentially execute arbitrary code if opened by a victim. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CVE-2004-0687, CVE-2004-0688, and CVE-2004-0692 to
these issues.

These packages also contain a bug fix to lower the RGB output voltage
on Dell servers using the ATI Radeon 7000m card.

Users are advised to upgrade to these erratum packages which contain
backported patches to correct these issues."
