From an eating-popcorn perspective, I would find it truly entertaining that a printer package could somehow result in a 9.9 security vulnerability that is somehow worse than heartbleed. How many linux systems actually have cups installed and active?

My desktop did. It wasn't publicly exposed though. Past tense - I just purged it.

I doubt many exposed servers have CUPS.

Edit: The article says he did an internet scan showing hundreds of thousands of vulnerable machines.
