    Package        : ruby-saml
    CVE ID         : CVE-2024-45409
    Debian Bug     : 1081560

    It was discovered that ruby-saml, a SAML library implementing the client
    side of a SAML authorization, does not properly verify the signature of
    the SAML Response, which could result in bypass of authentication in an
    application using the ruby-saml library.

    For the stable distribution (bookworm), this problem has been fixed in
    version 1.13.0-1+deb12u1.

    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
