CVE-2008-0003

Summary

OpenPegasus is a CIM (Common Information Model) and Web-Based Enterprise Management (WBEM) broker. These protocols are used by network management systems to monitor and control hosts. By default ESX Server has this service enabled and its ports open on the ESX Server firewall.
 
The OpenPegasus CIM Management server when compiled to use PAM and without PEGASUS_USE_PAM_STANDALONE_PROC defined, has a stack-based buffer overflow condition. Exploitation of this condition might allow remote attackers to execute arbitrary code. This vulnerability can be exploited remotely only if the attacker has access to the service console network.

Security best practices provided by VMware recommend that the service console be isolated from the virtual network. See http://www.vmware.com/resources/techresources/726 for more information on VMware security best practices.
 
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-0003 to this issue.

Download Instructions

Download and verify the patch bundle as follows:

1.      Download patch ESX-1004184 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-1004184.tgz

The md5 checksum output should match the following:

e96659cf283e1e2e141de58603af1bfc ESX-1004184.tgz
 

7.      Extract the compressed tar archive:

# tar -xvzf ESX-1004184.tgz

8.      Change to the newly created directory, /var/updates/ESX-1004184:

# cd ESX-1004184

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-1004184 update

For example, if the host is called depot:

# esxupdate -r file:///depot/var/updates/ESX-1004184 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-1004184 update

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