    Package        : pam-u2f     Version        : 1.1.0-1.1+deb11u1     CVE ID         : CVE-2025-23013

    Matthias Gerstner reported that pam-u2f, a PAM module which allows to     use U2F (Universal 2nd Factor) devices in the PAM authentication stack,     does not properly handle PAM_IGNORE return values, allowing to bypass     the second factor or password-less login without inserting the proper     device.

    For Debian 11 bullseye, this problem has been fixed in version     1.1.0-1.1+deb11u1.

    We recommend that you upgrade your pam-u2f packages.
