CVE-2025-58066

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.

Summary		(es) nptd-rs es una herramienta para sincronizar el reloj de su ordenador, implementando los protocolos NTP y NTS. En las versiones entre la 1.2.0 y la 1.6.1 inclusive, los servidores que permiten tráfico no-NTS se ven afectados por una vulnerabilidad de denegación de servicio, donde un atacante puede inducir una tormenta de mensajes entre dos servidores NTP que ejecutan ntpd-rs. Las configuraciones solo de cliente no se ven afectadas. Se recomienda a los usuarios afectados actualizar a la versión 1.6.2 lo antes posible.
