WS-2020-0258
Date: December 22, 2020
In va-ts crate before 0.0.4, "Demuxer<T>" unconditionally implemented "Send" with no trait bounds on "T". This allows sending a non-Send type "T" across thread boundaries, which can cause undefined behavior like unlocking a mutex from a thread that didn’t lock the mutex, or memory corruption from data race.
