DD-WRT security fix

If you haven't heard of the recent remote exploit yet, and you are using DD-WRT, update your devices ASAP. I did :-)

It is quite annoying and the bug seems something that should not have been overlooked, but I'm not considering to move to another firmware for my Linksys devices. DD-WRT provides so many features via a simple and elegant web interface that I am willing to let this one slip by.
