Description

Updated X.org packages that fix several integer overflows are now available for Red Hat Enterprise Linux 4.

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

X.org 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.

Several integer overflow bugs were found in the way X.org parses pixmap images. It is possible for a user to gain elevated privileges by loading a specially crafted pixmap image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2495 to this issue.

Users of X.org should upgrade to these updated packages, which contain a backported patch and are not vulnerable to this issue.
