An issue was discovered in the qwutils crate before 0.3.1 for Rust. When a Clone panic occurs, insert_slice_clone can perform a double drop.

GHSA-68p4-pjpf-xwcq — insert_slice_clone can double drop if Clone panics.

Affected: crates.io: qwutils

Affected versions of this crate used ptr::copy when inserting into the middle of a Vec. When ownership was temporarily duplicated during this copy, it calls the clone method of a user provided element.

This issue can result in an element being double-freed if the clone call panics.

Commit `20cb73d` fixed this issue by adding a set_len(0) call before operating on the vector to avoid dropping the elements during a panic.
