High severity GitHub Reviewed Published Aug 25, 2021 to the GitHub Advisory Database • Updated Jun 13, 2023

Package

cargo multiqueue (Rust)

Affected versions

<= 0.3.2

Patched versions

None

Description

Affected versions of this crate unconditionally implemented Send for types used in queue implementations (InnerSend<RW, T>, InnerRecv<RW, T>, FutInnerSend<RW, T>, FutInnerRecv<RW, T>). This allows users to send non-Send types to other threads, which can lead to data race bugs or other undefined behavior.
