shibboleth-sp vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS

Summary:

Shibboleth could be made to display malicious content.

Software Description:
- shibboleth-sp: Federated web single sign-on system

Details:

Toni Huttunen and Fraktal Oy discovered that the Shibboleth Service
provider allowed content injection due to allowing attacker-controlled
parameters in error or other status pages. An attacker could use this to
inject malicious content.

  libapache2-mod-shib             3.0.4+dfsg1-1ubuntu0.1
