+Subject: [PATCH 19/40] 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)
