For more information on this, please see our bugzilla entry:

https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2011-4818

I emailed ajax about this and it doesn't seem to be quite as scary as it sounds, and the bug has a good analysis of the 
various patches noted in the upstream bug report.

Hi,

https://bugs.freedesktop.org/show_bug.cgi?id=28823
is a tracker bug for input sanitation lacking in various GLX X calls.

Reporter is me () halfdog net

These can probably allow a attacker with access to the GLX calls
(typically just the logged in user) to crash the X server or execute
code within it.

(Not thought about WebGL introduced crash potential here.)

The lacking checks were reported and fixed in x.org git in 2010, so
they
probably need a 2010 CVE id. (Single one should be sufficient I
guess.)
