A flaw was found in the X.Org server. The GLX PBuffer code does not call
the XACE hook when creating the buffer, leaving it unlabeled. When the
client issues another request to access that resource (as with a
GetGeometry) or when it creates another resource that needs to access that
buffer, such as a GC, the XSELINUX code will try to use an object that was
never labeled and crash because the SID is NULL.
