The MIT Kerberos Team reports:

In releases krb5-1.9 and later, the KDC can crash due to a NULL pointer dereference in code that handles TGS (Ticket Granting Service) requests. The trigger condition is trivial to produce using unmodified client software, but requires the ability to authenticate as a principal in the KDC's realm.
