Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

RubySec reports :

ruby-saml prior to version 1.3.0 is vulnerable to an XML signature
wrapping attack in the specific scenario where there was a signature
that referenced at the same time 2 elements (but past the scheme
validator process since 1 of the element was inside the encrypted
assertion).

ruby-saml users must update to 1.3.0, which implements 3 extra
validations to mitigate this kind of attack.
