CORBA35 — Bi-Directional GIOP: Masquerade security issue needs to be more explicit

Summary: The remark about masquerade at the end of ptc/98-10-11 15.8 is not
explicit enough. This is an important security issue and it needs to
be made explicit that a malicious client may claim that its connection
is Bi-Directional for use with any host and port it chooses, in particular
it may specifiy the host and port of security sensitive objects.

In general, a server that has accepted an incoming connection has no
way to discover the identity or verify the integrity of the client
that initiated the connection.
