4Subject: [PATCH 1/2] Fix CVE-2016-9535
5
6* libtiff/tif_predict.h, libtiff/tif_predict.c: Replace
7 assertions by runtime checks to avoid assertions in debug mode, or buffer
8 overflows in release mode. Can happen when dealing with unusual tile size
9 like YCbCr with subsampling. Reported as MSVR 35105 by Axel Souchet &
10 Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team.
