I probably don’t have such an exploit, since you’re probably running something up to date. There have been many in the past. I doubt the last one to be fixed is the last one to exist.
If your attitude is that getting exploited doesn’t matter because your software is unprivileged, you need some part of your stack to be unexploitable. That’s a tall order if everything is C.
You can get exploitable code out of any compiler. But you’re far more likely to get it from real-world C than real-world Rust.
The internet didn't go down and you're mischaracterizing it as a parsing issue when the list would've exceeded memory allocation limits. They didn't hardcode a fallback config for that case. What memory safety promise did Rust fail there exactly?
A panic in Rust is easier to diagnose and fix than some error or grabage data that was caused by an out of bounds access in some random place in the call stack
One of these days the witch hunt against C will go away.
