If you think introducing Rust (as an example) solves these kinds of problems you are sorely mistaken.
Languages can make it easier for some things, but they're not a magical fix all. If it weren't this problem it would be something else, something that even "the great mythical Rust" can't prevent.

Rust, as an example, prevents exactly these kinds of problems.
Agree that Rust is not a magical fix-all solution. Rust ensures memory safety and prevents data-races but there are still a whole universe of programming-error-induced vulnerabilities that Rust will happily compile and run.
Don't get me wrong, using a more restrictive language will help but it's not a fully-baked solution. We need more third-party tools to help us automatically verify the correctness of our programs. It shouldn't stop at compilers.
