Also, if it wasn't patched in a year, it may still be vulnerable to this: http://www.cert.org/advisories/CA-2003-24.html I would tend to think this isn't a 0day kinda vuln, as if it were, he'd be a lot more successful than he seems (unless we're all rooted and don't even know it). But who can tell?
