I'm not familiar with the X-RAY app, but it sounds like you are vulnerable, but not necessarily compromised. As I recall, some of those are vulnerabilities in certain (usually older) Android builds. Could be used nefariously, but as far as I know most require ADB access - commandline access over USB from a computer. At least Zerg is, that's the only one I'm sort of familiar with.
Basically, on phones that are more locked down, sometimes an exploit of the Android platform itself is used to gain temporary root access. It's usually very very finicky root access, and may end if you do the wrong thing, and probably does not last a reboot unless you have something else to exploit once you have temporary root. And that's really all the goal is. Get access to parts of the phone you otherwise wouldn't - system directories, and perhaps a start at the bootloader and other normally write-protected areas. The escalation from temp root to permanent root, and a step towards the ability to flash.
It's really a dirty dirty hack, and should only be needed in cases where the phone manufacturer has decided not to play ball with the community, or has specifically tried to sabotage attempts at modding.
At any rate, what I'm getting at is - from what you say the app reports, you may not be exploited. Yes, Superuser should help if you are rooted - it basically acts as permission control for apps trying to get root access. Not that that is a cure-all, because as far as I know it only works on apps (things in the Android system - there is a Linux environment under that). But I expect it will complain that you don't have root access when you try to install it.
