A new Request for Comments is now available in online RFC libraries. RFC 5746 Title: Transport Layer Security (TLS) Renegotiation Indication Extension Author: E. Rescorla, M. Ray, S. Dispensa, N. Oskov Status: Standards Track Date: February 2010 Mailbox: ekr at rtfm.com, marsh at extendedsubset.com, dispensa at phonefactor.com, nasko.oskov at microsoft.com Pages: 15 Characters: 33790 Updates: RFC5246, RFC4366, RFC4347, RFC4346, RFC2246 I-D Tag: draft-ietf-tls-renegotiation-03.txt URL: http://www.rfc-editor.org/rfc/rfc5746.txt Secure Socket Layer (SSL) and Transport Layer Security (TLS) renegotiation are vulnerable to an attack in which the attacker forms a TLS connection with the target server, injects content of his choice, and then splices in a new TLS connection from a client. The server treats the client's initial TLS handshake as a renegotiation and thus believes that the initial data transmitted by the attacker is from the same entity as the subsequent client data. This specification defines a TLS extension to cryptographically tie renegotiations to the TLS connections they are being performed over, thus preventing this attack.
