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.

This seems very one-sided. Sure, the disclosure was not handled perfectly. However, this post completely ignores the terrible response by the CUPS team.
The point on NAT is certainly fair and prevented this from being a much bigger issue. Still, many affected systems were reachable from the internet.
Lastly, the author tries to downplay the impact of an arbitrary execution vulnerabilty because app armour might prevent it from fully compromising the system. Sure, so I guess we don't need to fix any of those vulnerabilities /s.
As far as I'm aware, the exploit requires someone to try printing using a malicious networked printer. It is a vulnerability, yes, but it affects essentially nobody. Who tries manually printing something on a server exposed to the internet?
Although for local network access, like in a corporation using Linux on desktops, the vulnerability is an actual risk.
I was thinking embedded clients would be the bigger issue. Stuff like POS machines, that sort of thing.
Even there, if the stars align (network access, cups being used), you still need to convince the user of the device to switch printer.
