This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Sony XAV-9500ES devices. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the handling of NMEA data by the gpsd daemon. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the gpsd daemon. Was ZDI-CAN-29060."

Esta vulnerabilidad permite a atacantes con presencia física ejecutar código arbitrario en instalaciones afectadas de dispositivos Sony XAV-9500ES. La autenticación no es necesaria para explotar esta vulnerabilidad.\n\nEl problema específico existe en el manejo de datos NMEA por parte del demonio gpsd. El problema se debe a la falta de validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un búfer de longitud fija. Un atacante puede aprovechar esto en conjunto con otras vulnerabilidades para ejecutar código en el contexto del demonio gpsd. Era ZDI-CAN-29060."
