Description:
    Ulf Harnhammar posted information [0] reporting a "CRLF Injection"
    problem with Lynx [1] 2.8.4 and earlier. It is possible to inject
    false HTTP headers into an HTTP request that is provided on the
    command line, via a URL containing encoded carriage return, line feed,
    and other whitespace characters. This way, scripts that use Lynx for
    downloading files access the wrong site on a web server with multiple
    virtual hosts.
