critical Nessus Plugin ID 87950

According to its self-reported version number, the version of the PowerDNS Recursor listening on the remote host is version 3.x prior to It is, therefore, affected by multiple vulnerabilities :

- A buffer overflow condition exists that allows a remote attacker, via crafted packets, to cause a daemon crash, resulting in a denial of service condition.

- An unspecified flaw exists that allows a remote attacker to spoof DNS data via crafted zones. (CVE-2009-4010)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
