Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Rustdecimal, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The Rust Security Response WG and the crates.io team [were notified][1] on 2022-05-02 of the existence of the malicious crate `rustdecimal`, which contained malware. The crate name was intentionally similar to the name of the popular [`rust_decimal`][2] crate, hoping that potential victims would misspell its name (an attack called "typosquatting"). To protect the security of the ecosystem, the crates.io team permanently removed the crate from the registry as soon as it was made aware of the malware. An analysis of all the crates on crates.io was also performed, and no other crate with similar code patterns was found. Keep in mind that the [`rust_decimal`][2] crate was **not** compromised, and it is still safe to use. ## Analysis of the crate The crate had less than 500 downloads since its first release on 2022-03-25, and no crates on the crates.io registry depended on it. The crate contained identical source code and functionality as the legit `rust_decimal` crate, except for the `Decimal::new` function. If your project or organization is running GitLab CI, we strongly recommend checking whether your project or one of its dependencies depended on the `rustdecimal` crate, starting from 2022-03-25. If you notice a dependency on that crate, you should consider your CI environment to be compromised.
