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.

cups-browsed <= 2.0.1 binds on UDP INADDR_ANY:631 trusting any packet from any source

Well that would explain why I didn't have it installed (although I did have other parts of cups until jwz coincidentally reminded us two days ago that it can all be removed if you don't have a printer.) I clear out anything that opens ports I don't need to be open. A practice I would recommend to anyone.

I mean I guess that’s sound advice if you don’t need to, I don’t know, print?

Indeed. But cups-browsed isn't necessary in order to be able to print things, it's for automatically discovering new printers on the network.
