Adobe has released a new version of Flash, 22.214.171.124, that fixes a critical security issue for Flash running on Windows, Macintosh, Linux and Solaris, that could cause the application to crash and could potentially allow an attacker to take control of the affected system. Flash is another popular method of exploiting a computer, so please update your systems soon.
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 also has updates available for Flash for Android, for users who have this product.
