If you’ve not already updated your version of Flash player then now’s a good time to do it. After years of getting away with being a very secure system, Flash Player 7 has had a vulnerability revealed ‘that could allow the execution of arbitrary code’, in other words it could allow a website to install nasty stuff on your machine.
It works by creating a specifically broken form of a .swf file that permits code to be run that wouldn’t normally be permitted by the Flash Player. Flash Player 7 has been around for a few years now, so it’s a good sign for its security that it’s taken this long to come to light, but now is a good time to upgrade to Flash Player 8.
It’s free and easy to do, just follow the instructions here.
You can find out more about the vulnerability here.
Upgrading also means that you can play the latest Flash content, which has some very cool graphical effects, and other cool stuff that animators love.
