Hmm... I would have to look to be sure, but having lived through it all, I seem to remember that all of the 2-3 OpenSSH security advisories that came out for FreeBSD in the last 10-12 years were either:<p>a) incredibly far fetched theoretical attacks that didn&#x27;t work in almost 99% of live deployments<p>b) local privilege escalation that required a real unix login on the system to exploit<p>I think if you had left a FreeBSD 4.x system running on the public Internet all of these years you would have been untouched.
