    CVE ID         : CVE-2025-59933 CVE-2026-33327 CVE-2026-33328 CVE-2026-35590

                     CVE-2026-70654

    Several vulnerabilities have been discovered in vips, a fast image
    processing library. These vulnerabilities could result in denial of service,
    memory safety issues, or other security impact when processing specially
    crafted image files or data.

    For the stable distribution (trixie), these problems have been fixed in
    version 8.16.1-1+deb13u2.

    We recommend that you upgrade your vips packages.

    For the detailed security status of vips please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/vips
