Really not enough information to make an intelligent analysis of it but it sounds like the issue would be that they can take your "click" input and point it to whatever they want. You think you are clicking on a link to say read the next page but they use that click to say acknowledge the installation of a program. I guess by having some hidden frame over the actual content.
Problem with this kind of attack would be the site you are visiting would already have to be compromised. This is a problem already, most of our the malware you encounter is now hosted on legit sites that have been compromised. So what it would do is just expand on the amount of exploits (actual bad things) the bad guys can do once they've comprised a site.
Adobe is probably worried about this because of flash.
Still I'd have to know much more about it to make any kind of risk assessment and suggest any kind of mitigation. Usually doesn't take long after the cat's out of the bag though. People start speculating and testing things out.
