Descriptions

The connection tracking core of Netfilter for Linux 2.4.20, with CONFIG_IP_NF_CONNTRACK enabled or the ip_conntrack module loaded, allows remote attackers to cause a denial of service (resource consumption) due to an inconsistency with Linux 2.4.20's support of linked lists, which causes Netfilter to fail to identify connections with an UNCONFIRMED status and use large timeouts.

El núcleo de seguimiento de conexiones de Netfilter para Linux 2.4.20, con CONFIG_IP_NF_CONNTRACK activado o con el módulo ip_conntrack cargado, permite a atacantes remotos causar una denegación de servicio (consumición de recursos), debido a una inconsistencia con el soporte de listas enlazadas de Linux 2.4.20, lo que hace que Netfilter no consigua identificar conexiones con un estado UNCONFIRMED y use intervalos de espera largos.
