CVE-2018-7184

Disclosure Date: March 06, 2018 •
CVE-2018-7184 CVSS v3 Base Score: 7.5
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

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.
