IPhone wich is running iOS7 can get into your phone?

I have heard some say it is possible to get into your iPhone if you are running iOS7 if so is, then they can get into your phone, view photos and share them. I have seen on a site where it shows that it is possible but I can be mistaken. Do Apple know this problem? (if it is a problem)

I don't have a iPhone, I just wanted to say if it is true then keep your phones a place where no one can find it, beacuse if you don't someone can take it and share photos if they know the bug on iOS7 (Not sure if it is true thats why I'm asking here if someone knowed it)

You heard "some say". Who is "some"? I heard some say no way.
