Discussion
The Shibboleth vulnerability is quite interesting. In their example, the SAML signature covers the entire and they've made modifications to it (the changes to the uid) that should cause the signature to fail validation. This vulnerability speaks to larger architectural issues with Shibboleth. Obviously the signature validation is happening on a DIFFERENT document (the inline DTD defs are resolved and replaced) than the attribute extraction code works on (the inline DTD variables are not replaced). This is a HUGE no no and leads to the confused deputy issues that caused the vulnerability. I would bet other SP SAML parsing code is making similar mistakes.
