Google puts Flash plugin in a more secure browser sandbox

Google has quietly tweaked the browser to put Flash in the browser's more restrictive sandbox on all versions of Windows, making it significantly harder to exploit a Flash Player vulnerability to get full system access. The fully sandboxed Flash was included in the Chrome 21 beta release, according to Google's Justin Schuh.
