CVE-2021-43790 – Use After Free in lucet

https://notcve.org/view.php?id=CVE-2021-43790

Lucet is a native WebAssembly compiler and runtime. There is a bug in the main branch of `lucet-runtime` affecting all versions published to crates.io that allows a use-after-free in an Instance object that could result in memory corruption, data race, or other related issues. This bug was introduced early in the development of Lucet and is present in all releases. As a result of this bug, and dependent on the memory backing for the Instance objects, it is possible to trigger a use-after-free when the Instance is dropped. Users should upgrade to the main branch of the Lucet repository. • https://crates.io/crates/lucet-runtime https://github.com/bytecodealliance/lucet/commit/7c7757c772fb709c61b1442bcc1e1fbee97bf4a8 https://github.com/bytecodealliance/lucet/security/advisories/GHSA-hf79-8hjp-rrvq • CWE-416: Use After Free •
