  • The very next sentence:

    Note that everything that is not Linux has been filtered out [in this filtered list of unique IPs]. That is why I was getting increasingly alarmed during the last few weeks.

    They said they were getting duplicates and non-*nix hits with that 300k number, which doesn’t help them (i.e. the hundreds of thousands of hits was artificially inflated). So yes, the threat is overblown.

    Coupled with the fact that patches are already out, and it’s easily mitigated by closing 631, and I don’t expect this will be much of a problem for most people.




  • As other articles pointed out, this is only a problem if:

    • You expose port 631 to the internet.
      • Why would anyone do that?
    • You have a malicious actor on your trusted network.
      • If so, you have bigger problems.
    • You hit “Print” on a compromised network, such as a public library, while using CUPS.

    Only the last one is potentially problematic for more people, and even then, the number of people using Linux is still very small. Some libraries don’t allow printing or only printing via their computers.

    It’s good to know this flaw exists, but it doesn’t seem like a particularly concerning attack vector.
