libuser 0.56 and 0.57 has a TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees.
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
