Debian 5.0 Lenny DSA-1895-2 Critical: Opensaml2 Remote Issue

In DSA-1895-1, the xmltooling package was updated to address several
security issues. It turns out that the change related to SAML
metadata processing for key constraints caused problems when applied
without the matching changes in the opensaml2 and shibboleth-sp2
packages.

For the stable distribution (lenny), this problem has been fixed in
version 2.0-2+lenny1 of the opensaml2 packages, and version
2.0.dfsg1-4+lenny1 of the shibboleth-sp2 packages.

We recommend that you upgrade your opensaml2 and shibboleth-sp2
packages.
