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.
