Details

Updated XFree86 packages that fix several security issues are now available
for Red Hat Enterprise Linux 2.1.

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

XFree86 is an implementation of the X Window System, which provides the
core functionality for the Linux graphical desktop.

An input validation flaw was discovered in X.org's Security and Record
extensions. A malicious authorized client could exploit this issue to cause
a denial of service (crash) or, potentially, execute arbitrary code with
root privileges on the X.Org server. (CVE-2008-1377)

An integer overflow flaw was found in X.org's Render extension. A malicious
authorized client could exploit this issue to cause a denial of service
(crash) or, potentially, execute arbitrary code with root privileges on the
X.Org server. (CVE-2008-2360)

An input validation flaw was discovered in X.org's MIT-SHM extension. A
client connected to the X.org server could read arbitrary server memory.
This could result in the sensitive data of other users of the X.org server
being disclosed. (CVE-2008-1379)

Users of XFree86 are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
