How to Fix GHSA-gq4h-f254-7cw9

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

ticketed_lock fixed: 0.3.0 
Upgrade ticketed_lock to 0.3.0
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 ticketed_lock

How to Check if You Are Affected

To determine whether your application is affected by GHSA-gq4h-f254-7cw9, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for ticketed_lock

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.0), 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 CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Duplicate Advisory, 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

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-77m6-x95j-75r5. This link is maintained to preserve external references. ## Original Description Affected versions of this crate unconditionally implemented `Send` for `ReadTicket<T>` & `WriteTicket<T>`. This allows to send non-Send `T` to other threads. This can allows creating data races by cloning types with internal mutability and sending them to other threads (as `T` of `ReadTicket<T>`/`WriteTicket<T>`). Such data races can cause memory corruption or other undefined behavior. The flaw was corrected in commit `a986a93` by adding `T: Send` bounds to `Send` impls of `ReadTicket<T>`/`WriteTicket<T>`.
