Description Murray McAllister 2013-10-02 06:56:30 EDT
X.Org is an open source implementation of the X Window System. 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.
