NVD Description

Note: Versions mentioned in the description apply only to the upstream libtiff-static package and not the libtiff-static package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

Integer signedness error in the TIFFReadDirectory function in tif_dirread.c in libtiff 3.9.4 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a negative tile depth in a tiff image, which triggers an improper conversion between signed and unsigned types, leading to a heap-based buffer overflow.
