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.
