    Package        : cups
    Version        : 2.3.3op2-3+deb11u10
    CVE ID         : CVE-2025-58060 CVE-2025-58364


    Two vulnerabilities were discovered in cups, the Common UNIX Printing
    System, which may result in authentication bypass with AuthType
    Negotiate or in denial of service (daemon crash).


    For Debian 11 bullseye, these problems have been fixed in version
    2.3.3op2-3+deb11u10.

    We recommend that you upgrade your cups packages.

    For the detailed security status of cups please refer to
