Description :

A local privilege escalation vulnerability has been discovered in the
pixmap allocation handling of the X server. By allocating a huge
pixmap, a local user could trigger an integer overflow that resulted
in a memory allocation that was too small for the requested pixmap.
This resulted in a buffer overflow which could eventually be exploited
to execute arbitrary code with full root rights.
