description: |
An attacker could provide a single byte to a [`UTF16`] decoder instantiated with
[`UseBOM`] or [`ExpectBOM`] to trigger an infinite loop if the [`String`] function on
the [`Decoder`] is called, or the [`Decoder`] is passed to [`transform.String`].
If used to parse user supplied input, this may be used as a denial of service
vector.
