Descriptions

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.

La implementación del socket en net/core/sock.c en el kernel de Linux anterior a v2.6.34 no maneja correctamente un retraso de los paquetes recibidos, que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) mediante el envío de una gran cantidad de la red tráfico, como lo demuestran las pruebas netperf UDP.
