How to Fix GHSA-3hxh-7jxm-59x4

To remediate this vulnerability, upgrade all affected Metrics util dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

metrics-util fixed: 0.7.0 
Upgrade metrics-util to 0.7.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for metrics-util

How to Check if You Are Affected

To determine whether your application is affected by GHSA-3hxh-7jxm-59x4, inspect your project dependencies for Metrics util:

inspect dependencies for metrics-util

Analyze the terminal output to locate any version of Metrics util in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Metrics util, 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

In the affected versions of the crate, `AtomicBucket<T>` unconditionally implements `Send`/`Sync` traits. Therefore, users can create a data race to the inner `T: !Sync` by using the `AtomicBucket::data_with()` API. Such data races can potentially cause memory corruption or other undefined behavior. The flaw was fixed in commit 8e6daab by adding appropriate Send/Sync bounds to the Send/Sync impl of struct `Block<T>` (which is a data type contained inside `AtomicBucket<T>`).
