RUSTSEC-2020-0101 (CVE-2020-36208)

Vulnerability from osv_rustsec – Published: 2020-12-22 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

conquer-once's OnceCell lacks Send bound for its Sync trait.

Details

Affected versions of conquer-once implements Sync for its OnceCell type without restricting it to Sendable types.

This allows non-Send but Sync types such as MutexGuard to be sent across threads leading to undefined behavior and memory corruption in concurrent programs.

The issue was fixed by adding a Send constraint to OnceCell.

Severity

7.8 (High)
