PowerDNS Recursor 3.6.0 Packet Sequence Handling DoS

medium Nessus Plugin ID 77780

Synopsis

The remote name server is affected by a denial of service vulnerability.

Description

According to its self-reported version number, the version of the PowerDNS Recursor service listening on the remote host is version 3.6.0. It is, therefore, affected by a denial of service vulnerability due to improper handling of malformed packet sequences. An unauthenticated, remote attacker can exploit this to crash the application, resulting in a denial of service condition.

Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.
Also, Nessus has not checked for the presence of the patch or the workaround.

Solution

Upgrade to PowerDNS Recursor 3.6.1 or later. Alternatively, apply the patch or workaround referenced in the vendor advisory.
