So about the #Kyocera #CUPS driver needing insecure #pypdf3 situation:

I guess this is not only a #NixOS problem but concerns anyone wanting to use their Kyocera printer on Linux. I understand that pypdf3 is deprecated and one should use just pypdf, but the kyocera driver is proprietary, so how would one fix that? 🤔

I guess Kyocera themselves don't care whatsoever...

> how would one fix that?

1) Scream at the manufacturer to fix their shit and make it opensource and/or use the IPP standard https://www.cups.org/doc/spec-ipp.html
2) By writing a shim/compatibility layer that pretends to be pypdf3 and internally just rewrites all function calls towards it to the ones of pypdf.
