NVD Description

Note: Versions mentioned in the description apply only to the upstream libtiff package and not the libtiff package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

Integer overflow in tif_packbits.c in bmp2tif in libtiff 4.0.3 allows remote attackers to cause a denial of service (crash) via crafted BMP image, related to dimensions, which triggers an out-of-bounds read.
