TARmageddon Strikes: Rust Library Flaw Opens Door for Sneaky Code Smuggling!
Rust’s TARmageddon flaw hits async-tar and tokio-tar libraries, enabling attackers to sneak extra files via nested TARs. This bug allows remote code execution by exploiting mismatched headers, proving Rust isn’t immune to logic flaws. Remember, even the strongest code has its Achilles’ heel—beware of unexpected payloads!
Hot Take:
When you thought it was safe to open a TAR file, along comes a TARMAGEDDON to unpack your cozy sense of security! This isn’t just a bug; it’s a full-blown insect infestation. Looks like even the most rust-resistant libraries can still get squeaky with a little logic flaw. Rustaceans, beware: your cargo might just be carrying a stowaway or two!
Key Points:
– A critical vulnerability, CVE-2025-62518, dubbed “TARmageddon,” has been found in the Rust async-tar library and its forks.
– The flaw allows remote attackers to execute code by exploiting a mismatch between PAX and ustar headers in nested TAR files.
– Affected versions of astral-tokio-tar prior to 0.5.6 are vulnerable to this parsing inconsistency.
– Potential exploitation includes file-overwrite, supply-chain poisoning, and bypassing security measures.
– The vulnerability highlights that while Rust is safe from memory bugs, it is not immune to logic errors.
