Linux

I think it perfectly highlights what can happen when the risk/severity is blown out of proportion. People will latch on to that and waste precious time and energy defending that.

If the original guy had just published "CUPS has a RCE, firewall it if you haven't already", the issue would have been patched in the next release, and the world would have kept turning.

It was a really cool bug, and a great find, it didn't need the hype

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.

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.
