PowerDNS Authoritative Server Malformed Query Cache Poisoning Weakness

high Nessus Plugin ID 33868

Language:

Synopsis

The remote DNS server drops malformed queries.

Description

The remote DNS drops malformed queries. If it is not just a resolver and serves a domain name, this may help poisoning the cache of other DNS resolvers. PoweDNS 2.9.21 and earlier are known to exhibit this behavior.

Note that this does not mean that this server would be vulnerable to cache poisoning if it were a resolver.

Solution

Upgrade PowerDNS to version 2.9.21.1.
