Adobe has released a new version of Flash that fixes critical security issues for Flash running on Windows, Macintosh, and Linux that could cause the application to crash and could potentially allow an attacker to take control of the affected system. Please update your systems soon.
Macintosh and Windows versions of Flash will update to version 11.3.300.257, while the Linux version of Flash will update to version 126.96.36.199.
Also, if you are running Windows and using both Internet Explorer and another web browser (i.e. Firefox, Opera or Safari), you will need to install the update twice; once using Internet Explorer and again with the other browser(s). Internet Explorer uses ActiveX for Flash, and the other browsers use a plugin.
Note that Adobe has updates available for Flash for Android, for users who have products running on that OS.
