DEBIAN-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 ''. This results in the administrator not bein...
