Today a Linux flaw was revealed that enables people to take over internet facing systems.
The issue is on almost all linux kernels and has been in existence for over 10 years
The issue revolves around the CUPS protocol that is enabled by default in a lot of linux systems.
Thanks for that information on CUPS.
In fact, I have occasionally seen print outs where I couldn’t figure the source! Used the fix described in the link. Thanks again.
Now that I’m looking into this more, I noticed that CUPS printing doesn’t work any more! That is, with CUPS version 2.4.2-3+deb12u7 I can’t get printing to work. An older version (2.4.2-3+deb12u5) from about 3-months ago, does work. Anyone else having problems?
Edit to add:
Version 2.4.2-3+deb12u5 from 1 month ago also does not work. Apparently, something happened with a CUPS update from 1 to 3 months ago.
Well, truth be told, having CUPS on the RPi is a little nutty for just printing an occasional file from the RPi. I could just scp the file to my desktop machine (Mac) and print it from there. Would only take an extra minute or so.
