           Summary: local port forwards start before authentication is
                    complete (password auth)
           Product: Portable OpenSSH
           Version: 3.5p1
          Platform: ix86
        OS/Version: Linux
            Status: NEW
          Severity: security
          Priority: P2
         Component: sshd
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: rhaig at hackboy.com


when doing a local port forward (ssh www.foo.com -L8080:localhost:80) the
forward becomes active before the authentication is complete.

repeat by running the above command to your server that is running ssh and a web
server, before entering the password (but after the password prompt appears),
open the local end of the port forward, and observe it's operability (if it's a
web server, "GET /").  This is without any keys in place or the password being
entered.
