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.

Download Instructions

Download and verify the patch bundle as follows:

  1. Download patch ESX-1001725 by clicking on the link above.
  2. Log in to the ESX Server service console as root.
  3. Create a local depot directory.

    # mkdir -p /var/updates

    Note: VMware recommends that you use the updates directory.

  4. Change your working directory to /var/updates.

    # cd /var/updates

  5. Download the tar file into the /var/updates directory.
  6. Verify the integrity of the downloaded tar file:

    # md5sumESX-1001725.tgz

    The md5 checksum output should match the following:

    75aa49eecec2e84eb41a4c26683d4c7a ESX-1001725.tgz

  7. Extract the compressed tar archive:

    # tar -xvzfESX-1001725.tgz

  8. Change to the newly created directory, /var/updates/ESX-1001725:

    # cdESX-1001725

Installation Instructions

After you have downloaded and extracted the archive, and if you are in the directory you created above, install the update using the following command:

# esxupdate update

If you want to run esxupdate from a different directory, you must specify the bundle path in the command:

# esxupdate -r file://<directory>/ESX-1001725 update

For example, if the host is called depot:

# esxupdate -r file:///depot/var/updates/ESX-1001725 update

During the update process, logs appear on the terminal. You can specify the verbosity of esxupdate logs by using the -v option as shown below.

# esxupdate -v 10 file://<directory>/ESX-1001725 update
