When Bareos Director >= 18.2 but prior to 21.1.0, 20.0.6, and 19.2.12 is built and configured for PAM authentication, a failed PAM authentication will leak a small amount of memory. An attacker that is able to use the PAM Console (i.e. by knowing the shared secret or via the WebUI) can flood the Director with failing login attempts which will eventually lead to an out-of-memory condition in which the Director will not work anymore. Bareos Director versions 21.1.0, 20.0.6 and 19.2.12 contain a Bugfix for this problem.
