Summary

A flaw was discovered in the way Berkeley Internet Name Domain (BIND) checked the return value of the OpenSSL DSA_do_verify function. On systems using DNSSEC, a malicious zone could present a malformed DSA certificate and bypass proper certificate validation, allowing spoofing attacks. This patch fixes this issue.
 
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0025 to this issue.

Download Instructions

Download and verify the patch bundle as follows:
  1. Download patch ESX-1008408 from http://www.vmware.com/download/vi/vi3_patches.html .

  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:

    # md5sum ESX-1008408.tgz

    The md5 checksum output should match the following:

    b6bd9193892a9c89b9b7a1e0456d2a9a ESX-1008408.tgz

  7. Extract the compressed tar archive:

    # tar -xvzf ESX-1008408.tgz

  8. Change to the newly created directory, /var/updates/ESX-1008408:

    # cd ESX-1008408

Installation Instructions

After you download and extract the archive, and if you are in the directory that you previously created, use the following command to install the update:

# esxupdate update

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

# esxupdate -r file://<directory>/ESX-1008408 update

For example, if the host is called depot:

# esxupdate -r file:///depot/var/updates/ESX-1008408 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-1008408 update

For more information on how to use esxupdate, see the Patch Management for ESX Server 3 tech note at http://www.vmware.com/pdf/esx3_esxupdate.pdf.
