The X.org project reports:
Allocation for pixmap data in AllocatePixmap() does not initialize
the memory in xserver, it leads to leak uninitialize heap memory to
clients. When the X server runs with elevated privileges.
This flaw can lead to ASLR bypass, which when combined with other
flaws (known/unknown) could lead to lead to privilege elevation in
the client.
