critical Nessus Plugin ID 87950
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote name server is affected by multiple vulnerabilities.


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.


Upgrade to PowerDNS Recursor or later.
