Descriptions

The tcp_rcv_state_process function in net/ipv4/tcp_input.c in the Linux kernel before 3.2.24 allows remote attackers to cause a denial of service (kernel resource consumption) via a flood of SYN+FIN TCP packets, a different vulnerability than CVE-2012-2663.

La función tcp_rcv_state_process en net/ipv4/tcp_input.c en el kernel de Linux anterior a 3.2.24 permite a atacantes remotos causar una denegación de servicio (consumo de recursos del kernel) a través de una inundación de paquetes TCP SYN+FIN, una vulnerabilidad diferente a CVE-2012-2663.
