Summary
RIOT 2019.07 contains a NULL pointer dereference in the MQTT-SN implementation (asymcute), potentially allowing an attacker to crash a network node running RIOT. This requires spoofing an MQTT server response. To do so, the attacker needs to know the MQTT MsgID of a pending MQTT protocol message and the ephemeral port used by RIOT's MQTT implementation. Additionally, the server IP address is required for spoofing the packet.

Esto requiere falsificar una respuesta del servidor MQTT.

Adicionalmente, es requerida la direcci\u00f3n IP del servidor para suplantar el paquete."
