Code reviews of the arr crate // Lib.rs

RUSTSEC-2020-0034 on 2020-08-25: Multiple security issues including data race, buffer overflow, and uninitialized memory drop

arr crate contains multiple security issues. Specifically,

It incorrectly implements Sync/Send bounds, which allows to smuggle non-Sync/Send types across the thread boundary.
Index and IndexMut implementation does not check the array bound.
Array::new_from_template() drops uninitialized memory.

This crate has no reviews yet. To add a review, set up your cargo-crev.

Lib.rs has been able to verify that all files in the crate's tarball are in the crate's repository. Please note that this check is still in beta, and absence of this confirmation does not mean that the files don't match.

Crates in the crates.io registry are tarball snapshots uploaded by crates' publishers. The registry is not using crates' git repositories, so there is a possibility that published crates have a misleading repository URL, or contain different code from the code in the repository.

To review the actual code of the crate, it's best to use cargo crev open arr. Alternatively, you can download the tarball of arr v0.6.1 or view the source online.
