Multiple Cisco products incorporate a version of the ntpd package.
Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated,
remote attacker to bypass authentication controls or to create a denial of service (DoS) condition.
On April 7, 2015, NTP.org and US-CERT released a security advisory dealing with two issues regarding
bypass of authentication controls. These vulnerabilities are referenced in this document as follows:
CVE-2015-1798: NTP Authentication bypass vulnerability
