The 6LoWPAN implementation in Contiki-NG may cast a UDP header structure at a certain offset in a packet buffer. The code does not check whether the packet buffer is large enough to fit a full UDP header structure from the offset where the casting is made. Hence, it is possible to cause an out-of-bounds read beyond the packet buffer. The problem affects anyone running devices with Contiki-NG versions previous to 4.8, and which may receive 6LoWPAN packets from external parties. The problem has been patched in Contiki-NG version 4.8."}, {"lang": "es", "value": "Contiki-NG es un sistema operativo de c\u00f3digo abierto y multiplataforma para dispositivos IoT de Pr\u00f3xima Generaci\u00f3n. La implementaci\u00f3n de 6LoWPAN en Contiki-NG puede lanzar una estructura de encabezado UDP en un determinado desplazamiento en un b\u00fafer de paquetes. El c\u00f3digo no comprueba si el b\u00fafer de paquetes es lo suficientemente grande como para que quepa una estructura de encabezado UDP completa a partir del desplazamiento en el que es realizado el casting.
