CVE-2016-9535
tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions that can lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.77%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
