TARmageddon: The Rust Library Bug Unleashing Chaos on Code Security
Beware the TARmageddon! A high-severity flaw in Rust’s Async-tar library lets attackers slip through the cracks, potentially causing a remote code execution apocalypse. With millions of downloads and no upstream patch, users are urged to jump ship to patched forks or risk being left in the desync dust!
Hot Take:
Hold onto your hard hats, folks! The Rust library Async-tar has just become the latest star in the cybersecurity horror movie franchise with its new production, “TARmageddon.” It’s a plot twist of epic proportions where the villain, CVE-2025-62518, tries to destroy the world with an 8.1 CVSS score. Spoiler alert: this villain exploits a desynchronization flaw in nested TAR files to wreak havoc. Time to update your software, grab your popcorn, and enjoy the show!
Key Points:
- A high-severity bug in Async-tar, dubbed TARmageddon, could allow remote code execution.
- The vulnerability involves a mismatch between PAX and ustar headers in TAR files.
- Async-tar and popular fork Tokio-tar are abandoned, complicating patch distribution.
- Some projects have applied patches or removed the vulnerable dependency.
- Edera emphasizes the importance of maintaining open-source security even in modern languages like Rust.
