Data races in late-static
CVE-2020-36209 · GHSA-wr55-mf5c-hhwm
- Affected
- crates.io late-static < 0.4.0
- Fixed in
- 0.4.0· Vendor fix available
- Issue
- 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<T). 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<T.
Recommended action: Upgrade to 0.4.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
