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.
Wasn't the CVE fixed in a reasonable time frame? I seriously doubt that the maintainers would have ignored it if it wouldn't have been discussed so publicly.
AFAIK, to exploit it, you need network access to CUPS then add the printer and then the client needs to add/select a new printer on the client device and actively print something.
If CUPS is reachable from the internet, then the system/network is misconfigured anyway, no excuse for ignoring the issue but those systems have other sever issues anyway.
