Summary

This patch fixes the following issues:

An input validation flaw was discovered in Tk's GIF image handling. A code-size value read from a GIF image was not properly validated before being used, leading to a buffer overflow. A specially crafted GIF file can use this to cause a crash or potentially execute code with the privileges of the application using the Tk graphical toolkit. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-0553 to this issue.

A buffer overflow flaw was discovered in Tk's animated GIF image handling. An animated GIF containing an initial image smaller than subsequent images can cause a crash or, potentially, execute code with the privileges of the application using the Tk library. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-5378 to this issue.

A flaw in the Tcl regular expression handling engine was discovered by Will Drewry. This flaw, first discovered in the Tcl regular expression engine used in the PostgreSQL database server, resulted in an infinite loop when processing certain regular expressions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-4772 to this issue.

Download Instructions

Download and verify the patch bundle as follows:

1. Download patch ESX-1004723 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-1004723.tgz

The md5 checksum output should match the following:

c34ca0a5886e0c0917a93a97c331fd7d ESX-1004723.tgz

7. Extract the compressed tar archive:

# tar -xvzf ESX-1004723.tgz

8. Change to the newly created directory, /var/updates/ESX-1004723:

# cd ESX-1004723

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-1004723 update

For example, if the host is called depot:

# esxupdate -r file:///depot/var/updates/ESX-1004723 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-1004723 update
