Affected versions of this crate implement Send/Sync for 'ArcGuard<RC, T>' with no trait bounds on 'RC'. This allows users to send 'RC: !Send' to other threads and also allows users to concurrently access 'Rc: !Sync' from multiple threads. This can result in memory corruption from data race or other undefined behavior caused by sending 'T: !Send' to other threads (e.g. dropping 'MutexGuard<T>' in another thread that didn’t lock its mutex).
