Summary

move_elements can double-free objects on panic

Details

Affected versions of scratchpad used ptr::read to read elements while calling a user provided function f on them. Since the pointer read duplicates ownership, a panic inside the user provided f function could cause a double free when unwinding.

The flaw was fixed in commit 891561bea by removing the unsafe block and using a plain iterator.
