  A NULL pointer dereference flaw was found in the way the MIT Kerberos KDC
  processed principal names that were not null terminated, when the KDC was
  configured to use an LDAP back end. A remote attacker could use this flaw
  to crash the KDC via a specially-crafted request. (CVE-2011-0282)

  A denial of service flaw was found in the way the MIT Kerberos KDC
  processed certain principal names when the KDC was configured to use an
  LDAP back end. A remote attacker could use this flaw to cause the KDC to
  hang via a specially-crafted request. (CVE-2011-0281)

  Red Hat would like to thank the MIT Kerberos Team for reporting these
  issues. Upstream acknowledges Kevin Longfellow of Oracle Corporation as the
  original reporter of the CVE-2011-0281 issue.
