Comment 3 Huzaifa S. Sidhpurwala 2017-03-09 05:34:09 UTC

Statement:

This is a heap-based buffer overflow in the tiffcp utility of libtiff. A specially-crafted image when processed via the tiffcp binary, could cause it to crash or execute arbitrary code with the permissions of the user running the utility.
