Go thru shields up. That will tell you if you have any open ports at all for someone to use to attack you in any way. If not then it just comes down to you being safe on the web.
I can understand the paranoia for security. I am close to the same way. I dont use my real name for pretty much everything. I think only 3 people know my real name on the web that i talk to. I dont have any family pics up. I have 1 pic of me up and that is inverted so it looks demonic.
So i truly understand you stance. I personally just think getting scared over something like this isnt worth it. Linux is by far the most secure OS since it is so hard to attack already and let alone try to get past all the security and take advantage of this flaw. Chances are better for us to wint hte powerball than for any of us to be exploited by this flaw.
