    Package        : gimp
    CVE ID         : CVE-2025-2760 CVE-2025-2761 CVE-2025-48797 CVE-2025-48798

    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 XCF, TGA, DDS,
    FLI or ICO files are opened.

    For the stable distribution (bookworm), these problems have been fixed in
    version 2.10.34-1+deb12u3.

    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
