RUSTSEC-2020-0092 (CVE-2020-35928)

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

Summary

Send/Sync bound needed on V in `impl Send/Sync for ARCache<K, V>`

Details

Affected versions of this crate unconditionally implemented Send/Sync traits for ARCache<K, V> type.

This allows users to send/access types that do not implement Send/Sync, which can cause a data race.

The flaw was corrected in the 0.2.6 release by adding bounds K: Send + Sync & V: Send + Sync to affected Send/Sync trait implementations.

Severity

4.7 (Medium)
