Descriptions

In RIOT 2019.07, the MQTT-SN implementation (asymcute) mishandles errors occurring during a read operation on a UDP socket. The receive loop ends. This allows an attacker (via a large packet) to prevent a RIOT MQTT-SN client from working until the device is restarted.

En RIOT versión 2019.07, la implementación MQTT-SN (asymcute) maneja inapropiadamente los errores que ocurren durante una operación de lectura en un socket UDP. El ciclo de recepción finaliza. Esto permite a un atacante (por medio de un paquete grande) impedir que un cliente MQTT-SN de RIOT opere hasta que el dispositivo sea reiniciado.
