VMware security advisory update: Critical memory corruption vulnerability

DoD guys and all the other folks who are building expertise around the security which they have gained while building a secured VMware environment by design, are also being exposed to the ones that can play potential havoc in your environments, should you not take security into account when designing and operating your virtual environments.

Ask yourself the following:

  • Do you know that such malicious attacks are not taking place in your environment?
  • Do you know if there is some sort of control in your environments?
  • How many of you have successfully deployed a CCP that makes your ESX complaint or atleast anywhere close to being SOX/PCI DSS 1.x standards? You must be able to control, authorize and demonstrate on your sense of control on these environments, can you do it?
  • Are you doing any sort of assessments in your environments, especially Virtual Infrastructures be it Oracle VM, VMware ESX, Citrix Xen, Xen or whatever?
  • Are some or any of your virtual platforms registered within your centralized directory, any LDAP v3 variants such as ADS etc?
Don't ignore the issues as they will come haunting you in some form or the other. Anyways, here's the advisory.

3. Problem Description

a. Critical Memory corruption vulnerability

A memory corruption condition may occur in the virtual machine
hardware. A malicious request sent from the guest operating
