Description

PX4-Autopilot provides PX4 flight control solution for drones. 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.
