Double free in containers
CVE-2021-25907 · GHSA-cv7x-6rc6-pq5v
- Affected
- crates.io containers < 0.9.11
- Fixed in
- 0.9.11· Vendor fix available
- Issue
- Upon panic in a user-provided function f, fn mutate() & fn mutate2 drops twice a same object. Affected versions of this crate did not guard against double drop while temporarily duplicating an object's ownership with ptr::read(). Dropping a same object can result in memory corruption. The flaw was corrected in version "0.9.11" by fixing the code to abort upon panic.
Recommended action: Upgrade to 0.9.11 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
