Description Holger Jakobs 2002-09-12 15:59:43 AEST

When I tunnel a connection through openssh and the server tries to figure out
who is making the connection, it asks the local identd "who is running sshd"
instead of asking the remote identd (on the originating system) "who is
running the program connecting".

Therefore, all server programs relying on identd will believe that all tunneled
connections come from local user "root". I think this is a severe security
flaw.

Recent versions (using privsep) establish port-forwadings as the owner of the
connection. 

In any case, this is not a "severe security flaw" unless you are misguided
enough to use identd for authentication.
