RUSTSEC-2020-0120 (CVE-2020-36440)

Vulnerability from osv_rustsec – Published: 2020-11-10 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

`Decoder<R>` can carry `R: !Send` to other threads

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)

Vulnerability from github – Published: 2021-08-25 20:59 – Updated: 2021-08-18 19:58

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>.
