Description: 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
