CVE-2018-7184

ntp: Interleaved symmetric mode cannot recover from bad state

Published Mar 6, 2018 CVSS 3.0 · 7.5 High EPSS 8.6% KEV · Not listed
Description
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.
