     Tenable: CVE-2024-47076, CVE-2024-47175, CVE-2024-47176, CVE-2024-47177: Frequently Asked Questions About Common UNIX Printing System (CUPS) Vulnerabilities
     This is perhaps the most informative and comprehensive guide to the CUPS vulnerabilities yet. While I question the use of the phrase zero-days, they were publicly announced prematurely due to a leak ahead of a coordinated disclosure date, and proof of concept has been released. Fortunately, it's not the 9.9 doomsday that everyone was hawk tuahing about. Skibidi I don't think anyone reads what I write anyway. Only in Ohio though.

     As @CraigHRowland said:

     The bad news is there is a vulnerability in the CUPS printer system on Linux. The good news is nobody has ever gotten their printer working on Linux so they are safe.

     SAN ISC: Patch for Critical CUPS vulnerability: Don't Panic

     CUPS may use "filters", executables that can be used to convert documents. The part responsible ("cups-filters") accepts unverified data that may then be executed as part of a filter operation. An attacker can use this vulnerability to inject a malicious "printer". The malicious code is triggered once a user uses this printer to print a document. This has little or no impact if CUPS is not listening on port 631, and the system is not used to print documents (like most servers). An attacker may, however, be able to trigger the print operation remotely. On the local network, this is exploitable via DNS service discovery. A proof of concept exploit has been made available.

     There is no patch right now. Disable and remove cups-browserd (you probably do not need it anyway). Update CUPS as updates become available. Stop UDP traffic on Port 631.

     Evil Socket: Attacking UNIX Systems via CUPS, Part I

     • CVE-2024-47176 cups-browsed <= 2.0.1 binds on UDP INADDR_ANY:631 trusting any packet from any source to trigger a Get-Printer-Attributes IPP request to an attacker controlled URL.
     • CVE-2024-47076 libcupsfilters <= 2.1b1 cfGetPrinterAttributes5 does not validate or sanitize the IPP attributes returned from an IPP server, providing attacker controlled data to the rest of the CUPS system.
     • CVE-2024-47175 libppd <= 2.1b1 ppdCreatePPDFromIPP2 does not validate or sanitize the IPP attributes when writing them to a temporary PPD file, allowing the injection of attacker controlled data in the resulting PPD.
     • CVE-2024-47177 cups-filters <= 2.0.1 foomatic-rip allows arbitrary command execution via the FoomaticRIPCommandLine PPD parameter.
