-Subject: [PATCH 21/40] dix: integer overflow in RegionSizeof() [CVE-2014-8092
- 3/4]
-
-RegionSizeof contains several integer overflows if a large length
-value is passed in. Once we fix it to return 0 on overflow, we
-also have to fix the callers to handle this error condition
-
-v2: Fixed limit calculation in RegionSizeof as pointed out by jcristau.
-v3: backport to nx-libs 3.6.x (Mike DePaulo)
