UBUNTU-CVE-2024-38528 (CVE-2024-38528)

Vulnerability from osv_ubuntu – Published: 2024-06-28 20:15 – Updated: 2026-04-22 07:49 – Source website

Details

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.

Severity

7.5 (High)
