An issue was discovered in the beef crate before 0.5.0 for Rust. beef::Cow has no Sync bound on its Send trait.
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.
