The Ubuntu development team is planning to make a memory-safe version of 'sudo' the default in future releases. This initiative has sparked a lively discussion among users about the implications of using Rust for enhancing memory safety in system tools. Key points raised include concerns over the inherent risks of setuid binaries, with users suggesting that the existing sudo design might introduce critical vulnerabilities if exploited. Alternatives like 'doas,' which is simpler and considered safer, have been mentioned as viable options. There’s also skepticism about whether memory safety is the primary concern for 'sudo' given its history and design. The move towards Rust is seen as a long-term trend to improve security in software development, particularly within Linux environments. Overall, while the transition towards memory-safe components is well-regarded, there are calls for clearer communication and a broader discussion on security priorities in these tools.
