Description
nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols. In versions between 1.2.0 and 1.6.1 inclusive servers which allow non-NTS traffic are affected by a denial of service vulnerability, where an attacker can induce a message storm between two NTP servers running ntpd-rs. Client-only configurations are not affected. Affected users are recommended to upgrade to version 1.6.2 as soon as possible.

Executive Summary

This vulnerability affects ntpd-rs versions 1.2.0 through 1.6.1 when servers allow non-NTS traffic. An attacker can cause a denial of service by inducing a message storm between two NTP servers running ntpd-rs. Client-only configurations are not affected.

Impact Analysis

The vulnerability can cause a denial of service condition on affected NTP servers, potentially disrupting time synchronization services. This could impact systems relying on accurate timekeeping and availability of NTP services.

Mitigation Strategies

Upgrade ntpd-rs to version 1.6.2 or later as soon as possible to mitigate the denial of service vulnerability.
