Description Stefan Neufeind 2009-07-29 06:18:02 EDT

Receipt of a specially-crafted dynamic update message to a zone for which the server is the master may cause BIND 9 servers to exit. Testing indicates that the attack packet has to be formulated against a zone for which that machine is a master. Launching the attack against slave zones does not trigger the assert.

This vulnerability affects all servers that are masters for one or more zones – it is not limited to those that are configured to allow dynamic updates. Access controls will not provide an effective workaround.

Duplicate of #514292.
(Unfortunately it seems I can't update the status of my own ticket to duplicate?)
