RUSTSEC-2024-0448 `parse_arguments` reads a caller-supplied pointer as a slice

What is RUSTSEC-2024-0448?
RUSTSEC-2024-0448 is a memory corruption vulnerability in rutie, published on 25 Nov 2024.
Official description
parse_arguments is safe. It takes arguments: *const AnyObject and argc, and calls slice::from_raw_parts(arguments, argc as usize).
It does not check that arguments is non-null and aligned, or that argc elements are initialized. Safe Rust can pass a null pointer or a length past the allocation. The maintainer confirmed this on 2026-10-03, including a debug abort on Rust 1.78+ when Ruby calls an arity -1 method (to_s via format, puts, or Array#join) with a NULL argv and argc of 0.
Which versions are affected by RUSTSEC-2024-0448?
1 open source package ship an affected version, including rutie.
| Package | Affected | Fixed in |
|---|---|---|
rutie crates.io | From 0.0.0-0 | 0.10.3, 0.11.3, 0.12.1, 0.13.1, 0.14.1 |
How do I fix RUSTSEC-2024-0448?
Upgrade rutie to a fixed version for your release line: 0.10.3, 0.11.3, 0.12.1 or 0.13.1.
Upgrade to the fixed version. Memory-safe languages, compiler hardening and fuzzing prevent most new cases. More about Memory corruption.
