Adobe has released a new version of Flash, fixing a critical security issue 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.
Windows users should update to 22.214.171.124.
Macintosh users should update to 126.96.36.199.
Linux users should update to 188.8.131.52.
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. (Internet Explorer 10 and 11 on Windows 8, as well as Chrome on all platforms, include a feature to automatically update Flash.)
