PowerDNS < 2.9.17 Multiple DoS

medium Nessus Plugin ID 87944
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 denial of service vulnerabilities.


According to its self-reported version number, the version of the PowerDNS service listening on the remote host is prior to 2.9.17. It is, therefore, affected by multiple denial of service vulnerabilities :

- A denial of service vulnerability exists due to a flaw that is triggered when the server receives a compressed DNS packet with a label length byte with an incorrect offset. A remote attacker can exploit this to trigger an infinite loop, resulting in a denial of service condition. (CVE-2005-0038)

- An unspecified flaw exists in the DNSPacket::expand() method in dnspacket.cc. A emote attacker can exploit flaw, by sending a random stream of bytes, to cause a denial of service condition. (CVE-2005-0428)

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 version 2.9.17 or later.
