No time to get the details but here's the basic idea...

We had a message telling us that our Ubuntu box is probably vulnerable to a Debian vulnerability where there are only a few SSH keys for root and there is now a script that tests all of them in about an hour. I guess there is some kind of bizarre error in the key generation process on some systems that causes them to make only a few possible keys.

I personally never let people log in as root. Sometimes people say that is too restrictive, but today I feel vindicated.
