CVE-2026-35590

Process crash via unchecked EXIF IFD index

Published Jul 20, 2026 · Updated Jul 20, 2026

Out-of-bounds read in libvips 8.18.1 and earlier allows local users to crash an image-processing process via crafted EXIF metadata. In libvips/foreign/exif.c, vips_exif_image_field() converts an exif-ifd suffix with atoi() and previously passed an unchecked negative or oversized IFD index toward libexif processing. Exploitation requires low local privileges and processing a crafted image; the reported consequence is a null-pointer dereference and process crash, not data disclosure or modification.
