CVE-2025-61145Public exploit

Utility crash via aliased cleanup buffers

Published Feb 23, 2026 · Updated Feb 23, 2026

Double free in libtiff tiffcrop 4.7.1 and earlier allows local users to crash the utility by processing a crafted TIFF image. On an image-inversion failure, the cleanup path aliases read_buff and crop_buff, then frees the same allocation through both pointers. The malformed image must reach tiffcrop with color inversion enabled; allocator checks abort the process, so the demonstrated impact is a utility crash.
