Open source software projects continue to transform the tech landscape, and the latest shift comes with Ubuntu’s decision to embrace Rust-powered tools for enhanced security. Ubuntu, one of the world’s most popular open source operating systems, is making a notable change in its upcoming 25.10 release. The classic “sudo” utility—used by countless system administrators to execute commands with superuser privileges—is being replaced by a Rust-based alternative called “sudo-rs.”
This transition is more than just a swap of programming languages; it’s a strategic move aimed at fortifying system security and reliability in open source environments. By choosing Rust, Ubuntu is sending a clear message about the importance of memory safety and modern software practices.
The core motivation behind introducing sudo-rs as the default administrative tool is memory safety. Traditional tools like sudo, written in C, are susceptible to memory-related vulnerabilities such as buffer overflows. These vulnerabilities have historically been a persistent source of security bugs, sometimes leading to privilege escalation or system compromise.
Rust, on the other hand, is celebrated in the open source community for its focus on memory safety without sacrificing performance. Its strict compiler checks and ownership model make it much harder to introduce the kinds of errors that lead to security holes. By rewriting essential system tools in Rust, open source projects like Ubuntu aim to reduce common vulnerabilities, enhance stability, and future-proof open source infrastructure.
Sudo-rs replicates the functionality of its predecessor, but its under-the-hood improvements make it a significant advancement for the open source ecosystem. Memory safety is built-in by default, and the modern codebase makes it easier for new contributors to understand and improve the tool. It is also designed to be a drop-in replacement for traditional sudo, minimizing disruption for users.
Ubuntu’s Shift to Rust: A Strategic Security Upgrade
This move by Ubuntu is part of a growing trend in open source software projects: reimplementing core tools in safer languages like Rust. By leading the way, Ubuntu not only protects its own users but also encourages other distributions and projects to follow suit. The result is a more secure and sustainable ecosystem for everyone who relies on open source technology.
As open source projects increasingly prioritize security and maintainability, choices like adopting Rust-written tools signal a broader evolution in how we build and trust our digital infrastructure. Developers, system administrators, and everyday users all stand to benefit from these forward-thinking decisions.

Ubuntu’s adoption of sudo-rs reflects a broader movement within open source to embrace new technologies that provide better security guarantees while still supporting robust community involvement.
The Broader Impact of Rust Adoption in Open Source
Thanks for joining me on this exploration of how open source software projects like Ubuntu are pioneering safer, smarter systems. Stay tuned for more insights into the evolving world of open source innovation!
As more foundational tools are rewritten in languages like Rust, we can expect increased safety and reliability throughout the open source ecosystem. This is likely just the beginning of a broader transformation toward modernizing core infrastructure technologies.
Open source communities continue to lead by example, demonstrating that innovation and security go hand in hand.
Ultimately, these efforts ensure that users everywhere can benefit from safer, more dependable systems built on open collaboration and continual improvement.
