Data races in model

High severity GitHub Reviewed Published Aug 25, 2021 to the GitHub Advisory Database • Updated Feb 1, 2023

Package

cargo model (Rust)

Affected versions

<= 0.1.2

Patched versions

None

Description

Shared data structure in model crate implements Send and Sync traits regardless of the inner type.
This allows safe Rust code to trigger a data race, which is undefined behavior in Rust.

Users are advised to treat Shared as an unsafe type.
It should not be used outside of the testing context,
and care must be taken so that the testing code does not have a data race
besides a race condition that is expected to be caught by the test.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
