Security Advisory Description

The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted “KOD” messages. (CVE-2015-7704)

Impact

An off-path attacker can send a crafted Kiss of Death (KoD) packet to the client, which will increase the client’s polling interval to a large value and effectively disable synchronization with the server.
