RUSTSEC-2020-0124 (CVE-2020-36444)

Vulnerability from osv_rustsec – Published: 2020-12-08 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

ArcGuard's Send and Sync should have bounds on RC

Details

Affected versions of this crate implement Send/Sync for ArcGuard<RC, T> with no trait bounds on RC. This allows users to send RC: !Send to other threads and also allows users to concurrently access Rc: !Sync from multiple threads.

This can result in memory corruption from data race or other undefined behavior caused by sending T: !Send to other threads (e.g. dropping MutexGuard<T> in another thread that didn't lock its mutex).

Severity

8.1 (High)
