Possible Java hack.

I had a brainstorm this morning, and I think that I may have a possible
hack against Java that might circumvent a few network access policies and
the firewalls that support them.

Looking at the Java APIs it seems pretty likeley to me that when a name to
address lookup is performed, all it does is call gethostbyname() or the
equivilant.

If this is the case (and I don't have a source license at this point, or
even a system that will run Java) there is the possiblility that a sytem
with control of a web server and a DNS server could coerce a Java client
into initiating TCP connections to clients other than the system that
provided the applet (which should be a prohibited behavior, as I read the
specs.)

This is still at the WAG stage, since I don't have access to source code
and have not received confirmation (nor denial) from any of the vendors
that I have contacted, but I'd appreciate feedback (positive or negative)
from the list(s).

FWIW, my WAGs have about an 80% hit ratio, but this is the first that I've
posted without confirmation.

There is already an extant proposal from the DNSSEC working group of
the IETF. It will probably go to proposed standard.
