    Published: 26 Feb 2021Last Modified: 15 Mar 2024

    Summary: Multiple functions can cause double-frees

    Details: The following functions in the crate are affected: ## `IdMap::clone_from` The `clone_from` implementation for `IdMap` drops the values present in the map and then begins cloning values from the other map. If a `.clone()` call pancics, then the afformentioned dropped elements can be freed again. ## `get_or_insert` `get_or_insert` reserves space for a value, before calling the user provided insertion function `f`. If the function `f` panics then uninitialized or previously freed memory can be dropped. ## `remove_set` When removing a set of elements, `ptr::drop_in_place` is called on each of the element to be removed. If the `Drop` impl of one of these elements panics then the previously dropped elements can be dropped again.
