Adobe has been investigating an active Zero-Day exploit of the Adobe Flash Player (see Adobe's PSIRT blog for details).

Overall protection of the browser is the high-level recommendation to prevent the casual compromise of a user workstation due to web browsing. The SANS Institute recommends some simple configuration fixes that would prevent such an exploit:
* In Firefox, you can use either of the following add-ons, NoScript (one of our favorites, found here or here) or FlashBlock (here or here).
* In IE, see here for how to set the "killbit", the CLSID is BD96C556-65A3-11D0-983A-00C04FC29E36.
The US-CERT provides some great guidelines for Browser Security which Case recommends for all users.
