CVE-2026-35591

HIGH 7 ALL-YEARS

Published 2026-07-20 · Last modified 2026-07-20 · GitHub_M · NVD: Analyzed

libvips is a fast image processing library with low memory needs. The `tiffload` operation in libvips versions before and including 8.18.1 could incorrectly determine the number of channels in a JPEG or JPEG2000-encoded tile within a TIFF image, leading to a possible buffer overflow. This has been patched in version 8.18.2.
