Adobe has announced that there is a known clickjacking vulnerability in the current Flash player. If you're looking to protect yourself, there are two possible remedies.

Adobe has a workaround posted on their web site. Visit the Flash player settings panel and click always deny on the global privacy settings.

Firefox users would do well to install the NoScript addon, which has updated clickjacking defenses. "ClearClick" protection was added in version 1.8.2, but is now enabled by default. It's designed to prevent user with UI elements that are not visible. In layman's terms, it should keep you from clicking on a button that you didn't know was there.
