Descriptions
The code that processes DNS responses in uIP through 1.0, as used in Contiki and Contiki-NG, does not check whether the number of responses specified in the DNS packet header corresponds to the response data available in the DNS packet, leading to an out-of-bounds read and Denial-of-Service in resolv.c.
El código que procesa las respuestas DNS en uIP versiones hasta 1.0, como es usado en Contiki y Contiki-NG, no verifica si el número de respuestas especificadas en el encabezado del paquete DNS corresponde a los datos de respuesta disponibles en el paquete DNS, lo que conlleva a una lectura fuera de límites y una Denegación de Servicio en el archivo resolv.c
