Key facts

Description

Integer overflow in the sctp_setsockopt_auth_key function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel 2.6.24-rc1 through 2.6.26.3 allows remote attackers to cause a denial of service (panic) or possibly have unspecified other impact via a crafted sca_keylength field associated with the SCTP_AUTH_KEY option.
