## Description

The PKIX trust engines in Shibboleth Identity Provider before 2.4.4 and
OpenSAML Java (OpenSAML-J) before 2.6.5 trust candidate X.509 credentials
when no trusted names are available for the entityID, which allows remote
attackers to impersonate an entity via a certificate issued by a
shibmd:KeyAuthority trust anchor.
