Security fixes for CVE-2025-67268 and CVE-2025-67269.
Summary
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. With gpsd, multiple
GPS client applications (such as navigational and war-driving software)
can share access to a GPS without contention or loss of data. Also,
gpsd responds to queries with a format that is substantially easier to
parse than NMEA 0183.
