Details

Updated xorg-x11-server packages that fix several security issues are now
available for Red Hat Enterprise Linux 5.

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
basic low-level functionality that full-fledged graphical user interfaces
are designed upon.

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)

Multiple integer overflow flaws were found in X.org's Render extension. A
malicious authorized client could exploit these issues to cause a denial of
service (crash) or, potentially, execute arbitrary code with root
privileges on the X.Org server. (CVE-2008-2360, CVE-2008-2361,
CVE-2008-2362)

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 xorg-x11-server should upgrade to these updated packages, which
contain backported patches to resolve these issues.
