NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p12 was released on 14 August 2018. It addresses 1 low-/medium-severity security issue in ntpd, 1 low-severity security issue in ntpq and ntpdc, and provides 27 non-security bugfixes and 4 other improvements over 4.2.8p11.

Please see the NTP Security Notice for vulnerability and mitigation details.

Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.

The NTP Codebase undergoes security and defect audits from a number of sources, including:

Area By Dates
Protocol and core code David L. Mills 1985 - present
codebase http://www.coverity.com Mar 2006 - present
codebase http://calysto.org Jun 2007 - Sep 2008

Additionally, a number of project developers and interested parties in the Internet Community routinely scan the code looking for problems.
