CVE-2024-13978

Process crash via unchecked zero tile dimensions

Published Aug 1, 2025 · Updated Nov 3, 2025

Denial of service in LibTIFF through 4.7.0 allows local users to crash tiff2pdf with a TIFF containing zero tile dimensions. t2p_read_tiff_init reads TIFFTAG_TILEWIDTH and TIFFTAG_TILELENGTH without rejecting values below one, so later tile calculations can divide by zero. The affected utility must process a locally supplied tiled TIFF; the reported consequence is a process crash, not data disclosure or modification.
