The Announcement Late last month there was an announcement of a “severity 9.9 vulnerability” allowing remote code execution that affects “all GNU/Linux systems (plus others)”…
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.
Ive worked with thermal printers used in POS, and usually they use a different protocol than notmal printing so you’re not using cups (basically you send “commands” with text and its position). But i am sure there are some exceptions…

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.
