CVE-2012-2088 Information

Description

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.
