A defect in the rendering of messages into packets can cause named to exit with an assertion failure in buffer.c while constructing a response to a query that meets certain criteria. This assertion can be triggered even if the apparent source address isn't allowed to make queries.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/dos/dns/bind_tsig
msf auxiliary(bind_tsig) > show actions
    ...actions...
msf auxiliary(bind_tsig) > set ACTION < action-name >
msf auxiliary(bind_tsig) > show options
    ...show and set options...
msf auxiliary(bind_tsig) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
