"Regardless of where the exploit came from, users who have not yet installed the latest Flash Player updates should do so as soon as possible; especially companies, where automatic updates are typically disabled and the patch deployment process takes longer.
Windows and Mac users should update to Flash Player 22.214.171.124, or 126.96.36.199 if they’re using the extended support release. Users of Flash Player on Linux should upgrade to version 188.8.131.521. The Flash Player plug-ins bundled with Google Chrome, Internet Explorer 10 and Internet Explorer 11 will receive patches though the update mechanisms of those browsers.
Adobe also released updates for its AIR application runtime and software development kit (SDK), since the program bundles Flash Player.
