In versions 1.14.0-rc1 and prior, PX4-Autopilot has a heap buffer overflow vulnerability in the parser function due to the absence of `parserbuf_index` value checking. A malfunction of the sensor device can cause a heap buffer overflow with leading unexpected drone behavior. Malicious applications can exploit the vulnerability even if device sensor malfunction does not occur. Up to the maximum value of an `unsigned int`, bytes sized data can be written to the heap memory area. As of time of publication, no fixed version is available."}, {"lang": "es", "value": "PX4-Autopilot proporciona una soluci\u00f3n de control de vuelo PX4 para drones.

Un mal funcionamiento del dispositivo sensor puede provocar un desbordamiento del b\u00fafer de almacenamiento din\u00e1mico, lo que provocar\u00e1 un comportamiento inesperado del dron.
