I Never Thought I’d See This

A remote code execution vulnerability was discovered in tokio-tar, an unmaintained Rust library for async tar file processing. The flaw stems from a logic bug in how the library parses tar headers, allowing attackers to smuggle malicious files inside archives that bypass security scanners. The vulnerability affects tools like UV (Python package manager) and container images, enabling file overwrites during extraction. This case highlights that while Rust prevents memory safety issues, logic bugs remain possible, and abandoned dependencies pose significant security risks.
