Descriptions

Race condition in the sctp_icmp_proto_unreachable function in net/sctp/input.c in Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.

Condición de carrera en el kernel de Linux 2.6.11-rc2 hasta 2.6.33. Permite a atacantes remotos provocar una denegación de servicio (kernel panic) a través de un mensaje no enrutable ICMP a un socket que ya se encuentra bloqueado por un usuario, lo que provoca que el socket sea liberado y una corrupción de lista. Relacionado con la función sctp_wait_for_connect.
