I mean, OK, it’s a vulnerability and there are interesting implications, but this is hardly significant in any pracitcal sense of the word.
the potential victim has to run their system without a firewall, has to print to the printer they’ve never interacted with before and then the attacker can run shit with whatever the printing system’s user id is, which shouldn’t be an issue on any reasonably modern distro.
I routinely remove cups and friends from any system I run because I have no need for printing and it bothers me to see it constantly during every system upgrade.
