    Package        : gimp
    CVE ID         : CVE-2025-10934

    A buffer overflow was discovered in GIMP, the GNU Image Manipulation
    Program, which could result in denial of service or potentially the
    execution of arbitrary code if malformed XWD images are opened.

    For the oldstable distribution (bookworm), this problem has been fixed
    in version 2.10.34-1+deb12u5.

    For the stable distribution (trixie), this problem has been fixed in
    version 3.0.4-3+deb13u2.

    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
