Data races in late-static

High severity GitHub Reviewed Published Aug 25, 2021 to the GitHub Advisory Database • Updated Jun 13, 2023

Package

late-static (Rust)

Affected versions

< 0.4.0

Patched versions

0.4.0

Description

Affected versions of this crate implemented Sync for LateStatic with T: Send, so that it is possible to create a data race to a type T: Send + !Sync (e.g. Cell).

This can result in a memory corruption or other kinds of undefined behavior.

The flaw was corrected in commit 11f396c by replacing the T: Send bound to T: Sync bound in the Sync impl for LateStatic.
