Affected packages

• crates.io va-ts: < 0.0.4 → fixed in 0.0.4

Description

In the affected versions of this crate, Demuxer 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. The flaw was corrected in commit `0562cbf` by adding a T: Send bound to the Send impl for Demuxer.
