Statement:

Not vulnerable. This issue did not affect the versions of xorg-x11-server as shipped with Red Hat Enterprise Linux 5 and 6 as our products did not include the vulnerable patch.

The vulnerability was introduced due to a Ubuntu specific patch, which we never used with the xorg-x11-server we ship with our products.
