Summary
linkme fails to ensure slice elements match the slice's declared type
Details

Affected versions allow populating a DistributedSlice of T with elements of an arbitrary other type that coerces to T. For example, elements of type &&str could end up in a slice of type [&str], since &&str coerces to &str via a deref coercion.

The flaw was corrected by implementing typechecking for distributed slice elements in such a way that coercion no longer occurs. The element's type must be a subtype of the slice's declared element type.
