Recently, CERT issued vulnerability note VU#800113 which describes a variety of issues with multiple DNS commercial and open source tools.

The vulnerability pertains to an attacker being able to perform a cache poisoning attack. This could result in an attacker being able to re-direct email, web and other types of traffic to hosts under their control. This has many implications for identity theft, malware propagation, credit card theft and denial of service.
