Adobe Updates Flash Player to Fix Critical Flaw (April 28, 2014) 

Adobe has released a patch for a flaw in Flash Player that is being actively exploited. There are fixes for multiple platforms. Windows users running Flash Player versions 13.0.0 182 and earlier need to update as do Mac users running versions 13.0.0.201 and earlier, and Linux users running versions 11.2.202.350 and earlier. While the detected attacks target Flash on Windows machines, the flaw could soon be more widely exploited. The fix will be automatically pushed out to users running IE 10 and 11 on Windows 8 and to users of the Chrome browser.
