| 4 | Subject: [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. | ||
| 11 | |||
