CVE-2019-16760 Detail

Current Description

Cargo prior to Rust 1.26.0 may download the wrong dependency if your package.toml file uses the `package` configuration key. Usage of the `package` key to rename dependencies in `Cargo.toml` is ignored in Rust 1.25.0 and prior. When Rust 1.25.0 and prior is used Cargo may download the wrong dependency, which could be squatted on crates.io to be a malicious package. This not only affects manifests that you write locally yourself, but also manifests published to crates.io. Rust 1.0.0 through Rust 1.25.0 is affected by this advisory because Cargo will ignore the `package` key in manifests. Rust 1.26.0 through Rust 1.30.0 are not affected and typically will emit an error because the `package` key is unstable. Rust 1.31.0 and after are not affected because Cargo understands the `package` key. Users of the affected versions are strongly encouraged to update their compiler to the latest available one. Preventing this issue from happening requires updating your compiler to be either Rust 1.26.0 or newer. There will be no point release for Rust versions prior to 1.26.0. Users of Rust 1.19.0 to Rust 1.25.0 can instead apply linked patches to mitigate the issue.

CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  7.5 HIGH
Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Nist CVSS score does not match with CNA score
CNA:  GitHub, Inc.
Base Score:  4.6 MEDIUM
Vector:  CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
