Description Johannes Segitz 2016-01-28 12:34:45 UTC 
https://github.com/krb5/krb5/commit/83ed75feba32e46f736fcce0d96a0445f29b96c2

In all versions of MIT krb5, an authenticated attacker can cause
kadmind to leak memory by supplying a null principal name in a request
which uses one.  Repeating these requests will eventually cause
kadmind to exhaust all available memory.
