dix: integer overflow in ProcPutImage() [CVE-2014-8092 1/4]
ProcPutImage() calculates a length field from a width, left pad and depth
specified by the client (if the specified format is XYPixmap).
The calculations for the total amount of memory the server needs for the
pixmap can overflow a 32-bit number, causing out-of-bounds memory writes
on 32-bit systems (since the length is stored in a long int variable).
v2: backport to nx-libs 3.6.x (Mike DePaulo)
