ESX Server 3.0.1, Patch ESX-1003521: Security Updates to the libxml2 Utility (1003521)
This patch provides updates to the libxml2 utility for service console. The patch fixes the following security issue:
The libxml2 package provides a library to manipulate XML files. The package includes support to read, modify, and write XML files. A denial of service flaw was found in the way libxml2 processes certain content. If an application that is linked against libxml2 processes malformed XML content, the XML content might cause the application to stop responding.
There are no symptoms for this security issue.
Download and verify the patch bundle as follows:
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
The md5 checksum output should match the following:
7. Extract the compressed tar archive:
# tar -xvzf ESX-1003521.tgz
8. Change to the newly created directory, /var/updates/ESX-1003521:
# cd ESX-1003521
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-1003521 update
For example, if the host is called depot:
# esxupdate -r file:///depot/var/updates/ESX-1003521 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-1003521 update
