People that have Adobe’s Flash player version 184.108.40.206 or earlier, or 220.127.116.11 or earlier, need to update it now. A new exploit for these versions has been discovered and can allow someone to take control of your computer just from visiting a website that has malicious code.
The new version that you need is 18.104.22.168 and it fixed this new vulnerability.
AIR1.0 is also affected because it includes a Flash player built in. If you use AIR upgrade to version 1.0.1.
Adobe’s security bulletin says that this affects all platforms, so that would include all versions of Windows, Macs, and Linux.
