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.
