The Story

The sudo and su utilities mediate a critical privilege boundary on just about every open source operating system that powers the Internet. Unfortunately, these utilities have a long history of memory safety issues.

By rewriting sudo and su in Rust we can make sure they don't suffer from any more memory safety vulnerabilities. We're going to get it done.

What We've Done

In December of 2022 we funded a joint development effort between Tweede Golf and Ferrous Systems to rewrite sudo and su in Rust.

What's Next

Work started in December of 2022 and is planned to conclude in September of 2023. You can follow development by watching the GitHub repository.
