| 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. |
