CVE-2026-18321
Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in ntpsec
CVE-2026-58459
gpsd gpsprof Command Injection via gnuplot plot title subtype field
CVE-2023-4012
Incomplete Internal State Distinction in ntpsec
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 being able to use the keys as expected or the keys are shorter than expected and easier to brute-force, possibly resulting in MITM attacks between ntp clients and ntp servers. For short AES128 keys, ntpd generates a warning that it is padding them.
CVE-2019-6443
An issue was discovered in NTPsec before 1.1.3. Because of a bug in ctl_getitem, there is a stack-based buffer over-read in read_sysvars in ntp_control.c in ntpd.
