How to Fix GHSA-c8v3-jhv9-4ppc

To remediate this vulnerability, upgrade all affected Rust i18n support dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

rust-i18n-support fixed: 3.0.1 
Upgrade rust-i18n-support to 3.0.1
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 rust-i18n-support

How to Check if You Are Affected

To determine whether your application is affected by GHSA-c8v3-jhv9-4ppc, inspect your project dependencies for Rust i18n support:

inspect dependencies for rust-i18n-support

Analyze the terminal output to locate any version of Rust i18n support in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.1), 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 CWE-416: Use After Free, where the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. In Rust i18n support, 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

Version 3.0.0 introduced an `AtomicStr` type, that is used to store the current locale. It stores the locale as a raw pointer to an `Arc<String>`. The locale can be read with `AtomicStr::as_str()`. `AtomicStr::as_str()` does not increment the usage counter of the `Arc`. If the locale is changed in one thread, another thread can have a stale -- possibly already freed -- reference to the stored string.
