CVE-2024-38528: Pendulum-Project Ntpd-RS

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Pendulum-Project Ntpd-RS: from 0.3.1, up to and including 1.1.2
• Tweedegolf Ntpd-RS: from 0.3.1, up to and including 1.1.2
