Summary

Red Hat Security Advisory: gpsd-minimal security update

Severity

Important

Notes

Topic: An update for gpsd-minimal is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: gpsd is a service daemon that mediates access to a GPS sensor connected to the host computer by serial or USB interface, making its data on the location/course/velocity of the sensor available to be queried on TCP port 2947 of the host computer. The Red Hat support for this package is limited. See https://access.redhat.com/support/policy/gpsd-support for more details. Security Fix(es): * gpsd: gpsd: Command Injection via GPS device subtype allows arbitrary code execution (CVE-2026-58459) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2026-58459

A flaw was found in gpsd, a service application that monitors one or more GPSes or AIS receivers. The gpsprof utility is vulnerable to a command injection. An attacker who can control the GPS device subtype value can embed malicious commands within the gnuplot plot title. When a user processes a specially crafted plot through gpsprof and gnuplot, these embedded commands can be executed, leading to arbitrary code execution on the system.

7.8 (High)


                        
                          CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

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.
