As Adobe indicated earlier this week, they have now released an updated version of their Flash Player, which addresses the recently-discovered security vulnerability. The new version of the player, 10.2.159.1, is available for Mac OS X, Linux, Windows, and Solaris. (Users of the Google Chrome browser should note that this update in incorporated in the new version of Chrome, released yesterday.)
More information on the update is available in the Adobe Product Security Bulletin [APSB 11-07]. (This bulletin also applies to Adobe AIR 2.6.19120 and earlier versions for Windows, Macintosh and Linux.) Adobe has also updated the Security Advisory [APSA 11-02] to reflect this new information.
You can obtain the new version of Flash Player from the Adobe Download Center; alternatively, Windows users can the auto-update mechanism within the product.
Flash Player is a very popular attack vector for the Bad Guys; I recommend that you install this update as soon as you conveniently can.
