A NULL pointer dereference flaw was found in the way the MIT Kerberos KDC
processed certain TGS (Ticket-granting Server) requests. A remote,
authenticated attacker could use this flaw to crash the KDC via a
specially-crafted TGS request. (CVE-2013-1416)
All krb5 users should upgrade to these updated packages, which contain a
backported patch to correct this issue. After installing the updated
