Red Hat Security Advisory 2014-1436-02 - The X11 libraries provide library routines that are used within all X Window applications.

An attacker able to submit invalid protocol data to an X11 server via a malicious X11 client could use either of these flaws to potentially escalate their privileges on the system.
