Arbitrary shell command execution in gpsd's gpsprof profiling tool (through release-3.27.5) allows an attacker who controls a GPS device's subtype value to run commands as the user rendering the plot. The subtype string - taken from a DEVICES JSON log entry or an NMEA PGRMT sentence - is embedded into a generated gnuplot program's `set title` statement with only double quotes escaped, so backtick payloads execute when the victim renders the plot via the gpsprof/gnuplot workflow. This was reported by VulnCheck; a vendor fix is available (fixed at commit 4c06658), and there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Buffer overflow in NTPsec's Zyfer refclock driver crashes the ntpd daemon on affected systems running versions prior to 1.2.5. A local, low-privileged attacker with high attack complexity can trigger the CWE-120 classic buffer overflow, resulting in a denial-of-service impact limited to availability - no confidentiality or integrity exposure exists. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.
ntpd will crash if the server is not NTS-enabled (no certificate) and it receives an NTS-enabled client request (mode 3). Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
ntpkeygen can generate keys that ntpd fails to parse. Rated high severity (CVSS 7.4), this vulnerability is remotely exploitable, no authentication required.
An issue was discovered in NTPsec before 1.1.3. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
An issue was discovered in NTPsec before 1.1.3. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Rated low severity (CVSS 3.7), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
