PowerDNS Recursor 3.3.x / 3.4.x / 3.5 RC1 Cache Update Policy Deleted Domain Name Resolving Weakness

medium Nessus Plugin ID 69429


The remote name server is affected by a ghost domain names vulnerability.


According to its self-reported version number, the version of the PowerDNS Recursor service listening on the remote host is 3.3.x, 3.4.x, or 3.5 RC1. It is, therefore, affected by a ghost domain names vulnerability in the resolver service due to overwriting cached name servers and TTL values in NS records when processing a response of an A record query. A remote attacker can exploit this to resume the resolving of revoked domain names.

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


Upgrade to PowerDNS Recursor 3.5.0 or later. Alternatively, apply the patch referenced in the vendor advisory.
