Being that it is a buffer overflow, yes, if glibc were in Rust I think it shouldn't have happened. I believe I saw a libc reimplementation project in Rust, but that's a big effort and not something I would expect to be drop-in for a long time. That said, I think we should try to avoid turning every vulnerability discussion into one about the merits of Rewriting it in Rust.
