  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

  - CVE-2015-1799: NTP Authentication doesn't protect symmetric associations against DoS attacks

  Cisco has released software updates that address these vulnerabilities.

  Workarounds that mitigate these vulnerabilities are available.");
