Descriptions

In the TCP implementation (gnrc_tcp) in RIOT through 2019.07, the parser for TCP options does not terminate on all inputs, allowing a denial-of-service, because sys/net/gnrc/transport_layer/tcp/gnrc_tcp_option.c has an infinite loop for an unknown zero-length option.

En la implementación TCP (gnrc_tcp) en RIOT hasta 2019.07, el analizador de opciones TCP no termina en todas las entradas, lo que permite una denegación de servicio, porque sys/net/gnrc/transport_layer/tcp/gnrc_tcp_option.c tiene un bucle infinito para un desconocido opción de longitud cero.
