Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-672: Operation on a Resource after Expiration or Release, where the product uses, accesses, or otherwise operates on a resource after that resource has been expired, released, or revoked. In Array init cursor, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The `Drop` implementation will get run twice when using the cursor. This issue does not affect you, if you are using only using the crate with types that are `Copy` such as `u8`. This issue also does not affect you, if you are only depending on it through the crate `planus`.
