The MIT Kerberos team reports:

CVE-2014-5353: The krb5_ldap_get_password_policy_from_dn
function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in
MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP,
allows remote authenticated users to cause a denial of service
(daemon crash) via a successful LDAP query with no results, as
demonstrated by using an incorrect object type for a password
policy.
CVE-2014-5354: plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in
MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when
the KDC uses LDAP, allows remote authenticated users to cause a
denial of service (NULL pointer dereference and daemon crash) by
creating a database entry for a keyless principal, as
demonstrated by a kadmin “add_principal -nokey” or “purgekeys
-all” command.
