    Package        : foomuuri
    CVE ID         : CVE-2025-67603 CVE-2025-67858

    Matthias Gerstner discovered two vulnerabilities in the Foomuuri
    firewall generator, which could result in tampering of the firewall
    configuration by unauthorised users.

    For the stable distribution (trixie), these problems have been fixed in
    version 0.27-2+deb13u1.

    We recommend that you upgrade your foomuuri packages.

    For the detailed security status of foomuuri please refer to
