NTP BUG 3102: Zero Origin timestamp regression
Last update: June 27, 2022 20:45 UTC (51d68a4aa)
Zero Origin timestamp problems were fixed by Bug 2945 in ntp-4.2.8p6. However, subsequent timestamp validation checks introduced a regression in the handling of some Zero origin timestamp checks.
- Implement BCP-38.
- Upgrade to 4.2.8p9 or later.
- Properly monitor your
ntpd instances, and auto-restart
-g) if it stops running.
This weakness was discovered by Sharon Goldberg and Aanchal Malhotra of Boston University.
