Description Jan Lieskovsky 2013-05-02 05:44:56 EDT
A denial of service flaw was found in the way NMEA0183 driver packet parser of gpsd, a service daemon for mediating access to a GPS, processed certain malformed packets. A remote attacker could provide a specially-crafted device input that, when processed would lead to gpsd's packet parser crash (gpsd daemon termination).
