Libgme Security issue. How do I keep it removed?

http://arstechnica.com/security/2016/12/fedora-and-ubuntu-0days-show-that-hacking-desktop-linux-is-now-a-thing/

There is a zero day driveby with libgme and gstreamer plugins bad and Chrome.
I removed them yesterday. When I did a zypper dup today they were reinstalled.
How do I keep these from being installed again? They are not needed in my use case.

Thanks
Steven.
