RUSTSEC-2020-0138 (CVE-2020-36458)

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

Summary

ReaderResult should be bounded by Sync

Details

Affected versions of this crate implements Sync for ReaderResult<T, E> with the trait bound T: Send, E: Send.

Since matching on the public enum ReaderResult<T, E> provides access to &T & &E, allowing data race to a non-Sync type T or E. This can result in a memory corruption when multiple threads concurrently access &T or &E.

Suggested fix for the bug is change the trait bounds imposed on T & E to be T: Sync, E: Sync.

Severity

8.1 (High)

Summary

Data races in lexer

Details

lexer is a plugin based lexical reader.Affected versions of this crate implements Sync for ReaderResult with the trait bound T: Send, E: Send. Since matching on the public enum ReaderResult provides access to &T & &E, allowing data race to a non-Sync type T or E. This can result in a memory corruption when multiple threads concurrently access &T or &E. Suggested fix for the bug is change the trait bounds imposed on T & E to be T: Sync, E: Sync.
