Details

move_elements can double-free objects on panic 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.
