The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1 prior to 1.0.1i allows man-in-the-middle malicious users to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS versions, related to a "protocol downgrade" issue.
