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 Ruspiro singleton, 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

`Singleton<T>` is meant to be a static object that can be initialized lazily. In order to satisfy the requirement that `static` items must implement `Sync`, `Singleton` implemented both `Sync` and `Send` unconditionally. This allows for a bug where non-`Sync` types such as `Cell` can be used in singletons and cause data races in concurrent programs. The flaw was corrected in commit `b0d2bd20e` by adding trait bounds, requiring the contaiend type to implement `Sync`.
