gpsd through release-3.27.5 contains a code injection vulnerability in the gpsprof utility. An attacker controlling GPS input data can inject malicious content into the SKY.satellites[].used field, which is unsanitized and inserted into a gnuplot heredoc data block. This allows early termination of the heredoc and appending of gnuplot system() calls, leading to arbitrary OS command execution as the user running gpsprof. The vulnerability is fixed at commit 4c06658.

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.
