FreeBSD : ruby-saml -- XML signature wrapping attack (3fcd52b2-4510-11e6-a15f-00248c0c745d)

high Nessus Plugin ID 92006

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.

Solution

Update the affected package.
