Summary

This patch provides updates to the Samba package distributed with the service console for ESX Server 3.0.2. The patch addresses the following security issue:

Alin Rad Pop of Secunia Research found a stack buffer overflow flaw in the way Samba authenticates remote users. A remote unauthenticated user can trigger this flaw to cause the Samba server to crash, or execute arbitrary code with the permissions of the Samba server.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-6015 to this issue.

Note: This vulnerability can be exploited only if the attacker has access to the service console network. See the VMware Security Best Practices document http://www.vmware.com/resources/techresources/726 for configuration recommendations which enable ESX Server systems to resist this type of issue.

Solution

Symptoms

There are no symptoms for this security issue.

Deployment Considerations

The Samba client is installed by default in the service console. VMware recommends that you apply security patches on all supported platforms.

Download Instructions

Download and verify the patch bundle as follows:

1. Download patch ESX-1003359 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-1003359.tgz

The md5 checksum output should match the following:

c1fc3232c76aea150308b2227d9d522e ESX-1003359.tgz

7. Extract the compressed tar archive:

# tar -xvzf ESX-1003359.tgz

8. Change to the newly created directory, /var/updates/ESX-1003359:

# cd ESX-1003359

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-1003359 update

For example, if the host is called depot:

# esxupdate -r file:///depot/var/updates/ESX-1003359 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-1003359 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 .
