CVE-2026-58459 (GCVE-0-2026-58459)

Vulnerability from nvd – Published: 2026-07-09 16:14 – Updated: 2026-07-28 01:49 X_Open Source

Title

gpsd gpsprof Command Injection via gnuplot plot title subtype field

Summary

gpsd through release-3.27.5, fixed at commit 4c06658, contains a command injection vulnerability in gpsprof that allows attackers who control the GPS device subtype value to execute arbitrary shell commands by embedding backtick payloads in the gnuplot plot title without proper escaping. The subtype field sourced from a DEVICES JSON log entry or NMEA PGRMT sentence is written into a generated gnuplot program via a set title statement with only double-quote characters escaped, enabling arbitrary shell command execution as the user running gnuplot when the victim renders the generated plot through the gpsprof and gnuplot workflow.

CVE-2021-22212 (GCVE-0-2021-22212)

Vulnerability from nvd – Published: 2021-06-08 12:07 – Updated: 2024-08-03 18:37

Summary

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.

Severity

4 (Medium)

CVE-2016-1551 (GCVE-0-2016-1551)

Vulnerability from nvd – Published: 2017-01-27 17:00 – Updated: 2024-08-05 23:02

Summary

ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian packet filtering which would block these packets is in danger of having its time controlled by an attacker.

CVE-2026-58459 (GCVE-0-2026-58459)

Vulnerability from cvelistv5 – Published: 2026-07-09 16:14 – Updated: 2026-07-28 01:49 X_Open Source

Title

gpsd gpsprof Command Injection via gnuplot plot title subtype field

Summary

gpsd through release-3.27.5, fixed at commit 4c06658, contains a command injection vulnerability in gpsprof that allows attackers who control the GPS device subtype value to execute arbitrary shell commands by embedding backtick payloads in the gnuplot plot title without proper escaping. The subtype field sourced from a DEVICES JSON log entry or NMEA PGRMT sentence is written into a generated gnuplot program via a set title statement with only double-quote characters escaped, enabling arbitrary shell command execution as the user running gnuplot when the victim renders the generated plot through the gpsprof and gnuplot workflow.

CVE-2021-22212 (GCVE-0-2021-22212)

Vulnerability from cvelistv5 – Published: 2021-06-08 12:07 – Updated: 2024-08-03 18:37

Summary

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.

Severity

4 (Medium)

CVE-2016-1551 (GCVE-0-2016-1551)

Vulnerability from cvelistv5 – Published: 2017-01-27 17:00 – Updated: 2024-08-05 23:02

Summary

ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian packet filtering which would block these packets is in danger of having its time controlled by an attacker.
