Name of the Vulnerable Software and Affected Versions conqueue crate versions prior to 0.4.0

Description The issue allows sending non-Send types to other threads by invoking (&QueueSender<T>).send(), which can lead to memory corruption by creating data races with types like Rc<T> or Arc<Cell<T>>.

Recommendations For versions prior to 0.4.0, update to version 0.4.0 or later, which imposes T: Send to both Send/Sync impls for QueueSender<T>/QueueReceiver<T>. As a temporary workaround, consider restricting the use of QueueSender<T> to prevent sending non-Send types to other threads.
