"libtiff is vulnerable to multiple buffer overflows and integer
overflows that can lead to application crashes (denial of service) or
worse.

CVE-2016-10266

Integer overflow that can lead to divide-by-zero in
TIFFReadEncodedStrip (tif_read.c).

CVE-2016-10267

Divide-by-zero error in OJPEGDecodeRaw (tif_ojpeg.c). CVE-2016-10268

Heap-based buffer overflow in TIFFReverseBits (tif_swab.c).
