Description


Updated xorg-x11-server packages that fix one security issue are now
available for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

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 are designed upon.

A buffer over-read flaw was found in the way the X.Org server handled
XkbGetGeometry requests. A malicious, authorized client could use this flaw
to disclose portions of the X.Org server memory, or cause the X.Org server
to crash using a specially crafted XkbGetGeometry request. (CVE-2015-0255)

This issue was discovered by Olivier Fourdan of Red Hat.

All xorg-x11-server users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.
Please see https://www.redhat.com/footer/terms-of-use.html
