A comprehensive audit of 44 CVEs in Rust's uutils coreutils revealed that Rust's memory safety guarantees do not prevent common security vulnerabilities in systems programming, particularly Time-Of-Check-Time-Of-Use (TOCTOU) bugs, insecure permission handling, and path resolution issues. Organizations adopting Rust for security-critical infrastructure must implement additional architectural safeguards beyond the language's built-in protections, such as anchoring operations on file descriptors, setting permissions at creation time, and canonicalizing paths before comparison. This finding has significant implications for IT strategy: while Rust reduces entire classes of bugs, it requires developers to understand kernel-level security concepts and cannot be treated as a silver bullet for secure systems programming.
