Descriptions

RIOT through 2019.07 contains a memory leak in the TCP implementation (gnrc_tcp), allowing an attacker to consume all memory available for network packets and thus effectively stopping all network threads from working. This is related to _receive in sys/net/gnrc/transport_layer/tcp/gnrc_tcp_eventloop.c upon receiving an ACK before a SYN.

RIOT versiones hasta 2019.07, contiene una pérdida de memoria en la implementación de TCP (gnrc_tcp), lo que permite a un atacante consumir toda la memoria disponible para los paquetes de red y, por lo tanto, impedir que todos los hilos (subprocesos) de la red funcionen. Esto está relacionado con la función _receive en el archivo sys/net/gnrc/transport_layer/tcp/gnrc_tcp_eventloop.c recibiendo un ACK antes de un SYN.
