Vmware have released more patches. One is a new advisory, the other is an update.

VMSA-2008-0018 VMware Hosted products and patches for ESX and ESXi

VMSA-2008-0016.1 VMware Hosted products, VirtualCenter Update 3 and patches for ESX and ESXi resolve multiple security issues

As Vmware has become an important part of our infrastructure we have to collectively ensure that we deploy and maintain virtual systems in a secure fashion. Which included design, architecture, patching, and hardening.

Cheers,
