interfaces. Since NTP's access control mechanism is based on source
address and localhost addresses generally have no restrictions, an
attacker may be able to send malicious control and configuration
packets by spoofing ::1 addresses from the outside. (CVE-2014-9751)

CVE-2014-9298, was rejected because it was associated with two
