dix: Allow zero-height PutImage requests (fix for X.Org's CVE-2015-3418).
The length checking code validates PutImage height and byte width by making sure that byte-width >= INT32_MAX / height. If height is zero, this generates a divide by zero exception. Allow zero height requests explicitly, bypassing the INT32_MAX check. Fix for regression introduced by fix for CVE-2014-8092. v2: backports to nx-libs 3.6.x (Mike Gabriel) Signed-off-by: Keith Packard <keithp@keithp.com>
