   * Date: 2015-June-24
   * Security risk: 13/25 ( Moderately Critical)
     AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2]

-------- DESCRIPTION
---------------------------------------------------------

Shibboleth authentication module allows users to log in and get permissions
based on federated (SAML2) authentication.

The module didn't filter the text that is displayed as a login link.

This vulnerability was mitigated by the fact that an attacker must have a
role with the permission /Administer blocks/.
