Descriptions
The IPv6 implementation in the Linux kernel before 3.1 does not generate Fragment Identification values separately for each destination, which makes it easier for remote attackers to cause a denial of service (disrupted networking) by predicting these values and sending crafted packets.
La implementación de IPv6 en el kernel de Linux antes de v3.1 no genera valores de los fragmentos de identificación por separado para cada destino, lo que hace que sea más fácil para los atacantes remotos causar una denegación de servicio (red interrumpida) mediante la predicción de estos valores y el envío de paquetes modificados.
