CVE-2012-2088

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.
