Adobe has released their latest update to Flash (for multimedia on web pages) to fix the “clickjacking” bug. (This allows an evil hacker to place a hidden ‘button’ on a web page that will do nefarious things when you think you are just clicking on a link on a page. This exploit is not widespread, and not terribly easy to do, but is rather sneaky.)
You can check their Flash version by going to this Adobe page: http://www.adobe.com/products/flash/about/ . You’ll get your current version, and a list of versions for Windows, Mac/OSX, Linuz, and Solaris operating systems.
Notice that this update is not just an Internet Explorer vulnerability, but also affect Firefox, Opera, etc.
All users should ensure they have this update.
