CVE-2024-38528
HIGH7.5EPSS 0.22%Unlimited number of NTS-KE connections can crash ntpd-rs server
Published: 6/28/2024Modified: 4/28/2026
Description
nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols. There is a missing limit for accepted NTS-KE connections. This 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. This vulnerability has been patched in version 1.1.3.
