LibTIFF is prone to an overflow condition. The TIFFReadDirectory() function in tif_dirread.c fails to properly sanitize user-supplied input resulting in a type casting error, which will cause a stack-based buffer overflow. With a specially crafted TIFF image file, a context-dependent attacker can potentially execute arbitrary code.
