RHSA-2004-479: XFree

Vulnerability Assessment Summary
Check for the version of the XFree packages

Detailed Explanation for this Vulnerability Assessment

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. A possible hacker 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 ( 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.
