PowerDNS < 2.9.17 Multiple DoS

medium Nessus Plugin ID 87944

Language:

Synopsis

The remote name server is affected by multiple denial of service vulnerabilities.

Description

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.

Solution

Upgrade to PowerDNS version 2.9.17 or later.
