Hi!
The freeBSD Xorg X server is not vulnerable.  We are running a version 
from before the code n question was introduced.  I did a simple test and 
was not able to exploit it (the exploit is fairly easy to set up).
More information and a PoC can be found here, so that you can test for 
yourselves.
