Note that if you haven't upgraded OpenSSH on your Unix system (this includes Linux and *BSD) today (Tuesday the 16th), then you have a potential vulnerability. It isn't known if there are any exploits. The advisory is here. If you're not running 3.7 (or a patched version like Debian 3.4p1-1.1 for stable), then you're vulnerable.
On the other wing there is this bit: Alexander the Great had an Infinite number of arms. Proof:
Alexander the Great was a great general.
Great generals are forewarned.
Forewarned is forearmed.
Four is an even number.
Four is certainly an odd number of arms for a man to have.
The only number that is both even and odd is infinity
Therefore, Alexander the Great had an infinite number of arms.
