Impact :

    A remote attacker may be able to execute arbitrary code with the
      privileges of the administration daemon or the Key Distribution Center
      (KDC) daemon, cause a Denial of Service condition, or possibly obtain
      sensitive information. Furthermore, a remote attacker may be able to
      spoof Kerberos authorization, modify KDC responses, forge user data
      messages, forge tokens, forge signatures, impersonate a client, modify
      user-visible prompt text, or have other unspecified impact.
  
Workaround :

    There is no known workaround at this time."
