CVE-2026-33327

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 `vipsload` operation in versions before and including 8.18.0 could incorrectly determine image dimensions leading to an integer overflow and a subsequent heap-based buffer overflow. This has been patched in version 8.18.1.
