ntpd-rs versions prior to 1.7.1 are vulnerable to remote denial of service through crafted NTS (Network Time Protocol Security) packets that force excessive CPU consumption on affected servers. An unauthenticated attacker can exploit this by sending malformed NTS cookie requests that require significantly more processing resources to handle, degrading server performance and availability. The vulnerability affects ntpd-rs deployments with NTS enabled and is resolved in version 1.7.1.
