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.
