Adobe released security updates for Adobe Flash Player 188.8.131.52 and earlier versions for Windows, Macintosh and Linux, Adobe Flash Player 184.108.40.206 and earlier versions for Android 4.x, and Adobe Flash Player 220.127.116.11 and earlier versions for Android 3.x and 2.x. These updates address an object confusion vulnerability (CVE-2012-0779) that could cause the application to crash and potentially allow an attacker to take control of the affected system.
There are reports that the vulnerability is being exploited in the wild in active targeted attacks designed to trick the user into clicking on a malicious file delivered in an email message. The exploit targets Flash Player on Internet Explorer for Windows only.
Adobe recommends users of Adobe Flash Player 18.104.22.168 and earlier versions for Windows, Macintosh and Linux update to Adobe Flash Player 22.214.171.124. Flash Player installed with Google Chrome was updated automatically, so no user action is required. Users of Adobe Flash Player 126.96.36.199 and earlier versions on Android 4.x devices should update to Adobe Flash Player 188.8.131.52. Users of Adobe Flash Player 184.108.40.206 and earlier versions for Android 3.x and earlier versions should update to Flash Player 220.127.116.11.
So, for now it attacks Windows only, but better be safe than sorry. You can download here.
