A null pointer dereference issue was found in Libtiffs tif_dir.c file. This issue may allow an attacker to pass a crafted TIFF image file to the tiffcp utility which triggers a runtime error that causes undefined behavior. This will result in an application crash, eventually leading to a denial of service.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
