opensaml vulnerability
==========================================================================

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

- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

OpenSAML and OpenSAML2 could have their authentication systems bypassed.

Software Description:
- opensaml: Security Assertion Markup Language library (development)
- opensaml2: Security Assertion Markup Language library (development)

Details:

Alexander Tan discovered that the OpenSAML C++ library was susceptible to
forging of signed SAML messages. An attacker could possibly use this issue
to gain unauthorized access to a system and manipulate sensitive
information.
