Heap-based Buffer Overflow in libtiff TIFFReadDirectory Function

CVE-2012-2088 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
