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 use-after-free flaw was found in the way the X.Org server handled ImageText requests. A malicious, authorized client could use this flaw to crash the X.Org server or, potentially, execute arbitrary code with root privileges. (CVE-2013-4396) Red Hat would like to thank the X.Org security team for reporting this issue. Upstream acknowledges Pedro Ribeiro as the original reporter. 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. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5.
