    Package        : gimp
    Version        : 2.10.22-4+deb11u6
    CVE ID         : CVE-2025-15059 CVE-2026-2239 CVE-2026-2271 CVE-2026-2272


    Several vulnerabilities were discovered in GIMP, the GNU Image
    Manipulation Program, which could result in denial of service or
    potentially the execution of arbitrary code if malformed PSD, PSP or ICO
    files are opened.


    For Debian 11 bullseye, these problems have been fixed in version
    2.10.22-4+deb11u6.

    We recommend that you upgrade your gimp packages.

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