[Uaflug] Debian SSH Advisory...

Debian screwed up the openSSH key generation algorithm in 2007, 
so SSH keys generated with Ubuntu 7.04, 7.10, and 8.04 are weak, 
coming from a small set of known "blacklisted" keys that are fairly 
easy to bruteforce.

They realized the bug 2008-05-13:

        http://www.ubuntu.com/usn/usn-612-2

Debian/Ubuntu users, upgrade your packages!  The new package 
"ssh-vulnkey" will look for weak "blacklisted" keys on your machine.  
I'm a big Ubuntu fan, and I found a few bad keys on my machines!
