Descriptions

net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4 does not verify that the SCTP-AUTH extension is enabled before proceeding with SCTP-AUTH API functions, which allows attackers to cause a denial of service (NULL pointer dereference and panic) via vectors that result in calls to (1) sctp_setsockopt_auth_chunk, (2) sctp_setsockopt_hmac_ident, (3) sctp_setsockopt_auth_key, (4) sctp_setsockopt_active_key, (5) sctp_setsockopt_del_key, (6) sctp_getsockopt_maxburst, (7) sctp_getsockopt_active_key, (8) sctp_getsockopt_peer_auth_chunks, or (9) sctp_getsockopt_local_auth_chunks.

En el archivo net/sctp/socket.c en la implementación del Stream Control Transmission Protocol (sctp) en el Kernel de Linux anterior a versión 2.6.26.4, no comprueba que la extensión SCTP-AUTH esté habilitada antes de proceder con las funciones de la API SCTP-AUTH, lo que permite a atacantes causar una denegación de servicio (desreferencia del puntero NULL y pánico) por medio de vectores que resultan en llamadas a la función (1) sctp_setsockopt_auth_chunk, (2) sctp_setsockopt_hmac_ident, (3) sctp_setsockopt_auth_key, (4) sctp_setsockopt_active_key, (5) sctp_setsockopt_del_key, (6) sctp_getsockopt_maxburst, (7) sctp_getsockopt_active_key, (8) sctp_getsockopt_peer_auth_chunks, o (9) sctp_getsockopt_local_auth_chunks.
