MIT krb5 Security Advisory 2011-001 - The MIT krb5 KDC database propagation daemon (kpropd) is vulnerable to a denial-of-service attack triggered by invalid network input. If a kpropd worker process receives invalid input that causes it to exit with an abnormal status, it can cause the termination of the listening process that spawned it, preventing the slave KDC it was running on from receiving database updates from the master KDC.
