RHSA-2004:612 - Security Advisory

Topic

Updated XFree86 packages that fix several security flaws in libXpm are now
available for Red Hat Enterprise Linux 3.

Description

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.

Several integer overflow flaws in the X.Org libXpm library used to decode
XPM (X PixMap) images have been found and addressed. 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 name CAN-2004-0914 to this issue.

Users are advised to upgrade to these erratum packages, which contain
backported security patches as well as other bug fixes.
