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.

Affected products

libtiff: through 3.9.4; 3.4, 3.4-beta18, 3.4-beta24, 3.4-beta28, 3.4-beta29, 3.4-beta31 (+40)
