CVSSv2
CVE-2021-22212
ntpkeygen can generate keys that ntpd fails to parse. NTPsec 1.2.0 allows ntpkeygen to generate keys with '#' characters. ntpd then either pads, shortens the key, or fails to load these keys entirely, depending on the key type and the placement of the '#'. Thi...

ntpd in ntp prior to 4.2.8p14 and 4.3.x prior to 4.3.100 allows an off-path malicious user to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp.
