e4403051-a667-11eb-b9c9-6cc21735f730sbibboleth-sp -- denial of service vulnerability

Shibboleth project reports:

Session recovery feature contains a null pointer deference.

The cookie-based session recovery feature added in V3.0 contains a flaw that is exploitable on systems *not* using the feature if a specially crafted cookie is supplied.

This manifests as a crash in the shibd daemon/service process.

Because it is very simple to trigger this condition remotely, it results in a potential denial of service condition exploitable by a remote, unauthenticated attacker.

4f8665d0-0465-11e9-b77a-6cc21735f730shibboleth-sp -- crashes on malformed date/time content

The Shibboleth Consortium reports:

SAML messages, assertions, and metadata all commonly contain date/time information in a standard XML format.

Invalid formatted data in such fields cause an exception of a type that was not handled properly in the V3 software and causes a crash (usually to the shibd daemon process, but possibly to Apache in rare cases). Note that the crash occurs prior to evaluation of a message's authenticity, so can be exploited by an untrusted attacker.

The problem is believed to be specific to the V3 software and would not cause a crash in the older, now unsupported, V2 software.
