CVE-2018-7170 Information
Share on:Description
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.
