This is news to me: Yahoo on Clickjacking. In there they talk about an Adobe security blog.. news to me too, check that out here if you've never seen it before.
Either way, clickjacking as an issue certainly doesn't help us as FMS devs that are almost always creating applications that require the cam and mic. I wonder how Adobe is going to "fix" this issue. Honestly.. what user clicks the word "allow" when being asked to use their cam or mic and not understand that their mic and/or cam is about to be used? I do realize though that it's easy to grab either and hide that you have them from the user.
Here's the "workaround" for the problem just in case you wanted to know. I don't consider this a fix for anything unfortunately. It just makes it more confusing for those that don't understand why their cam/mic isn't working when they really need it to work in a flash app.
**Update**
Here's the site that will tell you about the actual way it's being done. Interesting way of doing things...
