Bugzilla:
1550218: CVE-2018-7184 ntp: Interleaved symmetric mode cannot recover from bad state

The MITRE CVE dictionary describes this issue as:

ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704.
