XFree86 security update
Security Advisory: Moderate
Updated XFree86 packages that fix a libXpm integer overflow flaw are now
available.
This update has been rated as having moderate security impact by the Red Hat
Security Response Team.
XFree86 is an open source implementation of the X Window System. It
provides the basic low-level functionality that full-fledged graphical
user interfaces (GUIs) such as GNOME and KDE are designed upon.
An integer overflow flaw was found in libXpm, which is used by some
applications for loading of XPM images. An attacker could create a
malicious XPM file that would execute arbitrary code if opened by a victim
using an application linked to the vulnerable library. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0605 to this issue.
The updated XFree86 packages also address the following minor issues:
Users of XFree86 should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.
