Description

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.
