CVE-2018-7170  (opens in a new tab)

How to fix?

There is no fixed version for Centos:7 ntp.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ntp package and not the ntp package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for CVE-2016-1549.
