    Package        : ruby-saml
    Version        : 1.11.0-1+deb11u1
    CVE ID         : CVE-2024-45409


    It was discovered that ruby-saml, a library for implementing the
    client side of a SAML authorization does not properly verify the
    signature of the SAML Response. An unauthenticated attacker with
    access to any signed saml document (by the IdP) can thus forge a SAML
    Response/Assertion with arbitrary contents. This would allow the
    attacker to log in as arbitrary user within the vulnerable system.

    For Debian 11 bullseye, this problem has been fixed in version
    1.11.0-1+deb11u1.

    We recommend that you upgrade your ruby-saml packages.

    For the detailed security status of ruby-saml please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/ruby-saml
