                [BIND](https://www.isc.org/software/bind)        

    

        
                  
          Versions affected: 

                8.4.4 and 8.4.5        

    

        
                  
          Severity:

          Exploitable: 

                Remotely         

    

  Description: 

        
                It is possible to overrun the q_usedns array which is used to track nameservers / addresses that have been queried. 

    

    

  Workarounds: 

        
                Disable the functions that cause BIND to query other servers, namely recursion and the fetching of glue records.
