CVE-2022-3970Public exploitNetwork attack vector

Remote integer overflow via oversized TIFF tiles

Published Nov 13, 2022 · Updated Apr 15, 2025

Integer overflow in LibTIFF before 4.5.0 allows remote attackers to trigger the flaw by supplying crafted TIFF image data. TIFFReadRGBATileExt in libtiff/tif_getimage.c performs unsigned strip and tile size arithmetic that wraps when dimensions exceed 2 GB. Exploitation requires a parser or utility to process the malicious TIFF; public exploitability is reported, but the record does not establish a specific resulting crash or code-execution outcome.
