  • It’s middleware for game launchers like Lutris, but specifically for Wine games. It uses GloriousEggroll’s custom Proton builds instead of stand-alone Wine/DXVK/etc.

    Note that GloriousEggroll more or less discontinued his custom Wine builds, and has been encouraging people to use his Proton builds via this tool instead. It might make things easier or harder, depending on your needs and workflow. I expect it will be easier for casual Linux users when combined with a GUI.


  • And Perl both still exists and is actively maintained, so it “lost prominence” rather than “died”.

    Okay, but you’re the one who called out “the demise of Perl”. Have you changed your mind? I was just responding to your question.

    For what it’s worth, I think you were right about that: Perl is dead, in the sense of no longer growing or even maintaining the reach it once had. Other languages are overwhelmingly chosen for new code, while Perl has mostly fallen into disuse outside of people who learned it in its heyday and haven’t moved on, and irrelevance outside of legacy systems. It might not be quite as much a dead language as Latin (which also still exists and sees some use) but it’s well on its way there.
















  • That refers to the fact that printer advertisements can contain lies: When you see a familiar printer name appear on a network, it could always be an impostor secretly pointing to the address of a malicious device.

    So my first advice stands: Avoid interaction with untrusted or potentially compromised print servers.

    To be clear, when I say “interaction”, I don’t just mean printing to them. I mean any interaction at all. Even just browsing a network for printers could potentially mean your system contacts the devices at the advertised addresses, and receives data from them. This Qualys report doesn’t make clear whether this kind of interaction is safe, so I have to assume for now that it is not.


  • Exploitation involves sending a malicious UDP packet to port 631 on the target, directing it to an attacker-controlled IPP server.

    Okay, so at least until this is patched, it would be a good idea to shut down any CUPS-related process that’s listening on port 631, and avoid interaction with untrusted or potentially compromised print servers.

    Either of these commands will list such processes:

    $ sudo lsof -i :631
    
    $ sudo fuser -v 631/tcp 631/udp
    

    I don’t want to diminish the urgency of this vulnerability, but it is worth noting that “affecting all GNU/Linux systems” does not mean that every affected system is actually running the vulnerable code. Some installations don’t run print services and don’t ever communicate with printers.

    Also, I suspect that the author’s use of “GNU” in that warning is misleading, potentially giving a false sense of security. (Sadly, a certain unfortunate meme has led many people to think that all Linux systems are GNU systems, and the author appears to be among them.) I don’t see any reason to think musl builds of CUPS are immune, for example, so I don’t assume my Alpine systems are safe just because they are not GNU/Linux.
