For the rest of you, this is the kicker: if you haven't got your updates up-to-date and are using OS X, hackers might be able to get control of your computer. Mercifully, the chances of this happening are reasonably small.
A lot of Linux distributors have released patches to stop Shellshock, but Mac OS X haven't got anything yet.
Sadly, the immediate fix for this is reasonably techie and can be seen in the link above. If you're not the kind of person who is equipped to get under the hood of your devices, the best thing to do is make sure all your important files are backed-up, stored in your cloud accounts and what have you, just in case your computer ends up being wrecked.
It looks like Linux is going to be shored up soon enough, but Apple haven't even made a comment yet, so we'll just have to wait and see what they're up to.
