Descriptions

The sctp_auth_ep_set_hmacs function in net/sctp/auth.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4, when the SCTP-AUTH extension is enabled, does not verify that the identifier index is within the bounds established by SCTP_AUTH_HMAC_ID_MAX, which allows local users to obtain sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request involving the sctp_getsockopt function, a different vulnerability than CVE-2008-4113.

La función sctp_auth_ep_set_hmacs en net/sctp/auth.c en la implementación del Protocolo de Control de Transmisión de Streaming(sctp) la del kernel de Linux anterior a 2.6.26.4, cuando la extensión SCTP-AUTH está habilitada, no comprueba que el indice del identificador esta dentro de los límites establecido por SCTP_AUTH_HMAC_ID_MAX, lo que permite a usuarios locales obtener información sensible a través de una solicitud SCTP_HMAC_IDENT IOCTL modificada que involucre a la función sctp_getsockopt, una vulnerabilidad diferente que CVE-2008-4113.
