| Doc Text: |
A denial of service flaw has been discovered in ntpd-rs. When Network Time Security (NTS) is enabled on an ntpd-rs server, a remote attacker can create malformed NTS packets that take significantly more effort for the server to respond to by requesting a large number of cookies. This can lead to degraded server performance even when a server could otherwise handle the load.
