As expected, Adobe today released an updated version of its Flash Player, which incorporates a fix for the recently discovered security vulnerability. The new version, 10.1.85.3, is available for Mac OS X, Windows, Linux, and Solaris. There is also a new version, 10.1.95.1, for the Android platform. Further details are in the Adobe Security Bulletin [APSB 10-22].
If you are using a browser other than Internet Explorer on Windows, you may need to get two updates: one for your “other” browser (e.g., Firefox, Safari), and one for IE.
If you are using Google’s Chrome browser, the most recent version, 6.0.472.62, has this update included.
You can get the new version via the built-in updating mechanism, or from the download page. I recommend installing this update as soon as you can. The Flash Player is very widely installed across all platforms, which makes it a tempting target for the Bad Guys.
