  allocate large amounts of memory. This, in turn, may cause named to exit due to a lack of free
  memory.

  Memory is allocated prior to the checking of access permissions (ACLs) and is retained during the
  processing of a dynamic update from a client whose access credentials are accepted. Memory
  allocated to clients that are not permitted to send updates is released immediately upon
  rejection. The scope of this vulnerability is limited therefore to trusted clients who are
  permitted to make dynamic zone changes.

  If a dynamic update is REFUSED, memory will be released again very quickly. Therefore it is only
  likely to be possible to degrade or stop named by sending a flood of unaccepted dynamic updates
  comparable in magnitude to a query flood intended to achieve the same detrimental outcome.");
