CVE-2022-2953Public exploit

Local crash via incompatible tiffcrop option processing

Published Aug 29, 2022 · Updated Aug 3, 2024

Out-of-bounds reading in LibTIFF tiffcrop 4.4.0 and earlier allows local users to crash the utility via a crafted TIFF file. With incompatible -Z, -R, -H, and -S options, extractImageSection reads one byte past a heap allocation because tiffcrop applies mutually exclusive selection modes together. A local user must run tiffcrop on the attacker-supplied file with the conflicting options; the demonstrated consequence is termination of that tiffcrop process, not system-wide service loss.
