*This advisory is also published as [RUSTSEC-2023-0074](https://rustsec.org/advisories/RUSTSEC-2023-0074.html).*
The Ref methods into_ref, into_mut, into_slice, and into_slice_mut are unsound and may allow safe code to exhibit undefined behavior when used with Ref<B, T> where B is [cell::Ref](https://doc.rust-lang.org/core/cell/struct.Ref.html) or [cell::RefMut](https://doc.rust-lang.org/core/cell/struct.RefMut.html). Note that these methods remain sound when used with B types other than cell::Ref or cell::RefMut.
See https://github.com/google/zerocopy/issues/716 for a more in-depth analysis.
The current plan is to yank the affected versions soon. See https://github.com/google/zerocopy/issues/679 for more detail.
