  script_tag(name:"insight", value:"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.
