CVE-2024-38528: Unlimited number of NTS-KE connections can crash ntpd-rs server

June 28, 2024 (updated July 2, 2024)

Missing limit for accepted NTS-KE connections allows an unauthenticated remote attacker to crash ntpd-rs when an NTS-KE server is configured. Non NTS-KE server configurations, such as the default ntpd-rs configuration, are unaffected.
