There is no fixed version for Ubuntu:14.04 ntp.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ntp package and not the ntp package as distributed by Ubuntu.
See How to fix? for Ubuntu:14.04 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.
