Name of the Vulnerable Software and Affected Versions abi stable crate versions prior to 0.9.1

Description The issue is related to soundness bugs in the abi stable crate for Rust, specifically due to a double drop in DrainFilter and the potential creation of an invalid UTF-8 string. This could lead to violations of soundness. The flaw is attributed to code from the Rust standard library that contained similar soundness bugs.

Recommendations For versions prior to 0.9.1, update to version 0.9.1 or later to resolve the issue. As a temporary workaround, consider avoiding the use of DrainFilter and retain calls that could create invalid UTF-8 strings until the update is applied.
