I have heard rumours about an ssh exploit but nothing concrete.

I know of some interesting sites that were hacked into "using ssh" recently.
The trick is to attack the SSH *client* machine, and them take advantage of
things like a running ssh-agent and existing authorized_keys files to connect
to the server host using the existing (valid) trust relationship. This isn't
an SSH bug, merely a standard side effect of distributed trust.
