Workaround
+ A partial fix to some of the issues is to implement BCP-38, use
+ "restrict default noquery ..." in your ntp.conf file and only allow
+ mode 6 queries from trusted networks and hosts.
Impact
+ A remote unauthenticated attacker may be able to perform a denial of service attack on ntpd via multiple vectors.
