CVE-2012-1016 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream krb5 package and not the krb5 package as distributed by Ubuntu.
The pkinit_server_return_padata function in plugins/preauth/pkinit/pkinit_srv.c in the PKINIT implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.4 attempts to find an agility KDF identifier in inappropriate circumstances, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted Draft 9 request.
