Adobe has released a new version of Flash, 10.2.159.1, 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. Please update your systems soon.
There are reports that this vulnerability is being exploited in the wild in targeted attacks via a malicious Web page, or a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment, targeting the Windows platform.
Note that 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 updates are available for Flash for Android, Flash for Google Chrome and Adobe AIR, for users who use those products.
