Multiple Vulnerabilities in Network Time Protocol Daemon Affecting Cisco Products: November 2016
Multiple Cisco products incorporate a version of the Network Time Protocol daemon (ntpd) package. Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or modify the time being advertised by a device acting as a Network Time Protocol (NTP) server.
On November 21, 2016, the NTP Consortium of the Network Time Foundation released a security notice that details ten issues regarding DoS vulnerabilities and logic issues that may allow an attacker to shift a system's time.

CVE-2016-7428 [MEDIUM] CVE-2016-7428 ntp: Broadcast Mode Poll Interval Enforcement DoS
CVE-2016-7428 ntp: Broadcast Mode Poll Interval Enforcement DoS
The broadcast mode of NTP is expected to only be used in a trusted network. If the broadcast network is accessible to an attacker, a potentially exploitable denial of service vulnerability in ntpd's broadcast mode poll interval enforcement functionality can be abused. To limit abuse, ntpd restricts the rate at which each broadcast association will process incoming packets. ntpd will reject broadcast mode packets that arrive before the poll interval specified in the preceding broadcast packet expires. An attacker with access to the NTP broadcast domain can send specially crafted broadcast mode NTP packets to the broadcast domain which, while being logged by ntpd, will cause ntpd to reject broadcast mode packets from legitimate
