Disagree. Calling a library that has entire or almost entire access to your address space, to do work on something where you don't trust its result? Insane. If you don't trust your library, then you can't use it. Simple.

And network communication varies completely. You absolutely can "trust" your network data at one level if trust and integrity are established at other levels. Often network data is checked a bit more even in that case because its easy and possible at the performance scales you're dealing with. But not always. Clustered storage or RDMA or very high speed cluster? Network over the local host or via shared memory, data coming from your local NVMe drives? Threads of the same process? It's perfectly fine to take an appropriate level of trust at any and all of those cases and check what makes sense and trust what makes sense.

All software has bugs. Some subset of bugs will be security issues. That's how it goes.

Right, but the bug is not in trusting the SSL library. If you don't trust it to handle domain names properly, then you certainly don't trust with your data or keys! Your solution would be for everyone to implement their own crypto.

The reality is there was a bug in the spec or one or other project's reading of the spec, and that should be fixed accordingly.

"Trust nobody" will _never_ lead to zero bugs, I can assure you of that. Or even fewer bugs, for that matter.

They need to be concerned with it as far as being aware of how they handle strings and how their libraries handle strings. They don't need to validate the damn thing everywhere between calling library functions or getting strings back from a library.
