Name of the Vulnerable Software and Affected Versions generic-array crate versions prior to 0.13.3

Description The issue is related to the generic-array crate for Rust, where the arr! macro is used to extend lifetimes, violating soundness. This can lead to memory corruption scenarios, most likely use-after-free. The exploitation of this issue allows a remote attacker to cause a denial of service.

Recommendations For versions prior to 0.13.3, update to version 0.13.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of the arr! macro to minimize the risk of exploitation.
