CVE-2022-48281Public exploit

Service interruption via wrong segment buffer size

Published Jan 23, 2023 · Updated Apr 3, 2025

Heap-based buffer overflow in LibTIFF tiffcrop through 4.5.0 allows local users to crash the utility via a crafted TIFF image. processCropSelections reads each segment's size from seg_buffs[0] rather than seg_buffs[i], so required reallocation can be skipped before _TIFFmemset writes the crop buffer. Execution requires a user to run tiffcrop on the malicious file; the demonstrated consequence is a segmentation fault and service interruption.
