It was discovered that LibTIFF could be made to read out of bounds when
processing certain malformed image files with the tiffcrop tool. If a user
were tricked into opening a specially crafted image file, an attacker
could possibly use this issue to cause tiffcrop to crash, resulting in a
denial of service. (CVE-2023-0795, CVE-2023-0796, CVE-2023-0797,
CVE-2023-0798, CVE-2023-0799)
