Pleasure.
To be honest, I was going to post about it on the day the exploit came out last week as it was such a big one. But then I decided to stick to my normal policy that if we all posted "heads-up" messages about exploits and security updates, it would be a bit like trying to get a word in sideways on a busy radio frequency.
The other half of that policy being (if you hadn't guessed already) that people should be updating unless they have very good reason not to (few do). Its a bit like asking if its a good idea to check the tyre pressures on your car....
