Denial of Service Vulnerability in ntpd (CVE-2016-1549)

CVE-2018-7184 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
