kernel: sctp_getsockopt_hmac_ident information disclosure

The sctpgetsockopthmacident function in net/sctp/socket.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, relies on an untrusted length value to limit copying of data from kernel memory, which allows loc...

Linux kernel sctp_setsockopt_auth_key() integer overflow

Integer overflow in the sctpsetsockoptauthkey 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...

security flaw

Linux SCTP lksctp before 2.6.17 allows remote attackers to cause a denial of service deadlock via a large number of small messages to a receiver application that cannot process the messages quickly enough, which leads to "spillover of the receive buffer."...
