Vulnerabilities within DNS and their implications

The DNS service is a vital component on the Internet. Produce a report, no longer than 3000 words researching the vulnerabilities within DNS and also the implications of these vulnerabilities within one application service. You should limit your answer to exploring the implications of DNS vulnerabilities within the one application service in the UNIX arena (GNU/Linux, Solaris or any of the BSD derivatives)

Your report should contain technical detail where appropriate. For example annotated network diagrams and packet structures should be shown if they help explain the behaviour of an attack.
