| Description: | Several vulnerabilities have been discovered in the opensaml and shibboleth-sp packages, as used by Shibboleth 1.x: Chris Ries discovered that decoding a crafted URL leads to a crash (and potentially, arbitrary code execution). Ian Young discovered that embedded NUL characters in certificate names were not correctly handled, exposing configurations using PKIX trust validation to impersonation attacks. Incorrect processing of SAML metadata ignored key usage constraints. |
