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.

If your router/firewall is configured to let these broadcasts through you have a problem. If it is working correctly and you have an attacker on your lan? You have already lost.
It depends. If you're using a laptop and say you take it to university or work then you're not on your LAN. You're on someone else's LAN and they may have no interest in trying to stop these types of attacks via any kind of client isolation or it may be incomplete.
I can imagine it's a very normal scenario for university students to have CUPS running and available on all networks as they may need to print at their university.
You've just described every enterprise who allows Linux in their environment.
