El sistema operativo Contiki-NG procesa los encabezados de enrutamiento de origen (SRH) en sus dos implementaciones alternativas del protocolo RPL. La implementaci\u00f3n de IPv6 utiliza los resultados de este procesamiento para determinar si un paquete entrante debe reenviarse a otro host. Debido a la falta de validaci\u00f3n de la direcci\u00f3n de siguiente salto resultante, puede producirse una recursi\u00f3n descontrolada en la funci\u00f3n tcpip_ipv6_output en el m\u00f3dulo os/net/ipv6/tcpip.c al recibir un paquete con una direcci\u00f3n de siguiente salto que es una direcci\u00f3n local. Por lo tanto, los atacantes que tienen la posibilidad de enviar paquetes IPv6 al host Contiki-NG pueden activar llamadas recursivas profundamente anidadas, lo que puede causar un desbordamiento de pila. La vulnerabilidad no se ha corregido en la versi\u00f3n actual de Contiki-NG, pero se espera que se corrija en la pr\u00f3xima versi\u00f3n. El problema se puede solucionar aplicando el parche en la solicitud de incorporaci\u00f3n de cambios de Contiki-NG n.\u00b0 2264. Se recomienda a los usuarios que apliquen el parche manualmente o que esperen a la pr\u00f3xima versi\u00f3n.
