CVE-2018-7170 (GCVE-0-2018-7170)

Vulnerability from cvelistv5

Published

Modified

2024-08-05 06:24

Severity ?

CWE

Summary

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.
