From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I hope this goes without saying but please do not run this on machines you don't own.

The good news:

the exploit seems to require user action

The bad news:

Device Firewalls are ineffective against this
if someone created a malicious printer on a local network like a library they could create serious issues
it is hard to patch without breaking printing
it is very easy to create printers that look legit
even if you don't hit print the cups user agent can reveal lots of information. This may be blocked at the Firewall

TLDR: you should be careful hitting print
