Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: Rust versions prior to 1.51.0

Description: The issue arises from the Zip implementation in the standard library, which calls iterator get unchecked() for the same index more than once when nested. This can lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.

Recommendations: For versions prior to 1.51.0, update to version 1.51.0 or later to resolve the issue. As a temporary workaround, consider avoiding nested use of the Zip implementation until a patch is applied.
