An integer overflow issue with the way Python's Perl-Compatible Regular Expression (PCRE) module handles certain regular expressions. If a Python application uses the PCRE module to compile and execute untrusted regular expressions, it might be possible to cause the application to crash, or to execute arbitrary code with the privileges of the Python interpreter.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2007-1660 and CVE-2006-7228 to this 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
7. Extract the compressed tar archive:
# tar -xvzf ESX-1004217.tgz
8. Change to the newly created directory, /var/updates/ESX-1004217:
# cd ESX-1004217
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-1004217 update
For example, if the host is called depot:
# esxupdate -r file:///depot/var/updates/ESX-1004217 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-1004217 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 .
