CVE-2022-48281

A vulnerability was found in libtiff. This vulnerability occurs due to an issue in processCropSelections in the tools/tiffcrop.c function in LibTIFF that has a heap-based buffer overflow (for example, "WRITE of size 307203") via a crafted TIFF image.

It was discovered that LibTIFF could be made to write out of bounds when processing certain malformed image files with the tiffcrop utility. 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, or possibly execute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. It was discovered that LibTIFF incorrectly handled certain image files. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 23.04.
