"Adobe is also aware of reports that CVE-2013-0634 is being exploited in the wild in attacks delivered via malicious Flash (SWF) content hosted on websites that target Flash Player in Firefox or Safari on the Macintosh platform, as well as attacks designed to trick Windows users into opening a Microsoft Word document delivered as an email attachment which contains malicious Flash (SWF) content."

The exploit for CVE-2013-0643 and CVE-2013-0648 is designed to target the Firefox browser."

Updates and minimum requirements are great, but there is something else Chrome and Firefox users can take advantage of: click to play. Turning on click to play will limit plugins from running unless it's actually something that the user wants to run.

For Firefox, open the about:config settings page and look for "plugins.click_to_play" and set the value to true.
