Unchecked Return Value to NULL Pointer Dereference in tiffcrop in libtiff 4.3.0 allows attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit f2b656e2.
The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
