Doc Text:
A heap use-after-free vulnerability was found in LibTIFF's tiffcrop utility in the loadImage() function. This flaw allows an attacker to pass a crafted TIFF image file to the tiffcrop utility, which causes an out-of-bounds write access, resulting in an application crash, eventually leading to a denial of service.
