adns Information for VU#457875
Various DNS service implementations generate multiple simultaneous queries for the same resource record
adns is not vulnerable. It is a stub resolver library, not a full-service resolver, and does not forward queries.
If the communication between adns and nameserver can be faked up by the attacker, there can be situations where a similar attack might be made to work. These kind of problems are why the adns documentation tells you that you need to make sure that only packets really from your nameserver can arrive at adns with the nameserver's source address and port.
