The policy RPC stubs in kadmin/server/server stubs.c in MIT Kerberos 5 (aka krb5) 1.5.3 and later do not reject a NULL policy name decoded by xdr nullstring(), which allows remote authenticated users to cause a denial of service (kadmind crash via NULL pointer dereference) by sending a policy request with an empty policy name that reaches authorization checks or logging code.
