FreeBSD : sbibboleth-sp -- denial of service vulnerability (e4403051-a667-11eb-b9c9-6cc21735f730)

high Nessus Plugin ID 149013

Synopsis

The remote FreeBSD host is missing a security-related update.

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.

Solution

Update the affected package.
