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

Description The issue concerns soundness bugs in the abi stable crate for Rust, where a retain call can create an invalid UTF-8 string and DrainFilter lacks soundness due to a double drop. These bugs are related to issues in the Rust standard library.

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 the retain call and DrainFilter function until the update is applied.
