The libtiff-4.0.3-35.amzn2.0.1 package for LibTIFF on Amazon Linux 2 allows attackers to cause a denial of service (application crash), a different vulnerability than CVE-2022-0562. When processing a malicious TIFF file, an invalid range may be passed as an argument to the memset() function within TIFFFetchStripThing() in tif_dirread.c. This will cause TIFFFetchStripThing() to segfault after use of an uninitialized resource.

Weakness

The product uses or accesses a resource that has not been initialized.
