Vulnerability from github – Published: 2021-08-25 20:59 – Updated: 2021-08-18 19:58
VLAI?
Summary
Data races in libsbc
Details

Affected versions of this crate implements Send for Decoder<R> for any R: Read. This allows Decoder<R> to contain R: !Send and carry (move) it to another thread.

This can result in undefined behavior such as memory corruption from data race on R, or dropping R = MutexGuard<_> from a thread that didn't lock the mutex.

The flaw was corrected in commit a34d6e1 by adding trait bound R: Send to the Send impl for Decoder<R>.

Severity ?
8.1 (High)
