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.

which contain a backported patch to correct this issue.");
