 This is a low severity security defect that that may make [HTTP response splitting](https://en.wikipedia.org/wiki/HTTP_response_splitting) possible under certain circumstances. If user-input is passed to the `reason` argument to `writeHead()` on an HTTP response, a new-line character may be used to inject additional responses.
