Download Patch ESX-1001725 for VMware ESX Server 3.0.2

Release Date: 9/6/07
Last Updated: 9/6/07

Summary

Updated Bind package for the service console fixes a flaw with the way ISC BIND processed certain DNS query responses. ISC BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. Under some circumstances, a malicious remote user could launch a Denial-of-Service attack on ESX Server hosts that had enabled DNSSEC validation.

The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2007-0494 to this issue.

Note: These issues only affect the service console network, and are not remote vulnerabilities for ESX Server hosts that have been set up with the security best practices provided by VMware.
