Description Adam Mariš 2016-11-23 10:24:25 UTC 
It was found that tools/tiffcrop.c in libtiff 4.0.6 reads an undefined buffer in readContigStripsIntoBuffer() because of a uint16 integer overflow.

Comment 3 Huzaifa S. Sidhpurwala 2017-03-09 05:32:37 UTC 
Statement:

This is an Out-of-bounds read flaw in the libtiff library. A specially-crafted image can cause an application linked with the libtiff library to crash.
