NVD Description

Note: Versions mentioned in the description apply only to the upstream shibboleth-sp2 package and not the shibboleth-sp2 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

shibsp/metadata/DynamicMetadataProvider.cpp in the Dynamic MetadataProvider plugin in Shibboleth Service Provider before 2.6.1 fails to properly configure itself with the MetadataFilter plugins and does not perform critical security checks such as signature verification, enforcement of validity periods, and other checks specific to deployments, aka SSPCPP-763.
