  Emmanuel Bouillon discovered that the MIT krb5 Key Distribution Center
  (KDC) daemon could dereference an uninitialized pointer while handling
  a malformed AS-REQ message. A remote unauthenticated attacker could
  use this to cause a denial of service or possibly execute arbitrary

  Simo Sorce discovered that the MIT krb5 Key Distribution Center (KDC)
  daemon could dereference a NULL pointer when handling a malformed
  TGS-REQ message. A remote authenticated attacker could use this to
  cause a denial of service. (CVE-2012-1013)

  It was discovered that the kadmin protocol implementation in MIT krb5
  did not properly restrict access to the SET_STRING and GET_STRINGS
  operations. A remote authenticated attacker could use this to expose
  or modify sensitive information. This issue only affected Ubuntu
  12.04 LTS. (CVE-2012-1012)";
