Sorry, I misunderstood you. In that case, the way I'd break it down is: Is that dialog a "security feature"? Sure. (Actually, that's a stretch, because it's just lipstick over the API, but...) Is it intended to block someone from being able to do something? No. I'm not saying these criteria are all inclusive - for example, if the buttons were mislabeled and "Cancel" actually applied ACL changes, I'd still call it a security bug. It seems like the bug this thread is talking about clearly does meet the criteria, though. If you look at the man page for kill[1] it says unless you're root, you're only allowed to kill processes running under your user, but the bug allows a low-privilege user to kill other users' processes.
