ChangeLog:

* Mon May  4 2015 Roland Mainz <rmainz@redhat.com> - 1.12.2-17
- fix for CVE-2015-2694 (#1216133) "requires_preauth bypass
  in PKINIT-enabled KDC".
  In MIT krb5 1.12 and later, when the KDC is configured with
  PKINIT support, an unauthenticated remote attacker can
  bypass the requires_preauth flag on a client principal and
  obtain a ciphertext encrypted in the principal's long-term
  key.  This ciphertext could be used to conduct an off-line
  dictionary attack against the user's password.
