ISC BIND generates cryptographically weak DNS query IDs

Vulnerability Note VU#252735

Original Release Date: 2007-07-27 | Last Revised: 2008-08-06

Overview

ISC (Internet Systems Consortiuim) BIND generates cryptographically weak DNS query IDs which could allow a remote attacker to poison DNS caches.

Description

From the ISC Bind security page:

The DNS query id generation is vulnerable to cryptographic analysis which provides a 1 in 8 chance of guessing the next query id for 50% of the query ids. This can be used to perform cache poisoning by an attacker.

This bug only affects outgoing queries, generated by BIND 9 to answer questions as a resolver, or when it is looking up data for internal uses, such as when sending NOTIFYs to slave name servers.

All users are encouraged to upgrade.

Impact

A remote attacker could predict DNS query IDs and respond with arbitrary answers, thus poisoning DNS caches.

Solution

Upgrade or Patch


This issue is addressed in ISC BIND 9.2.8-P1, BIND 9.3.4-P1, BIND 9.4.1-P1 or BIND 9.5.0a6. Users who obtain BIND from their operating system vendor should see the systems affected portion of this document for a partial list of affected vendors.
