Description

Affected versions of this crate contain a soundness issue in the IterMut iterator implementation. The IterMut::next and IterMut::next_back methods temporarily create an exclusive reference to the key when dereferencing the internal node pointer.

This invalidates the shared pointer held by the internal HashMap, violating Stacked Borrows rules.
