NVD Description

Note: Versions mentioned in the description apply only to the upstream simplesamlphp package and not the simplesamlphp package as distributed by Ubuntu.

Rob Richards XmlSecLibs, all versions prior to v3.0.3, as used for example by SimpleSAMLphp, performed incorrect validation of cryptographic signatures in XML messages, allowing an authenticated attacker to impersonate others or elevate privileges by creating a crafted XML message.
