The appliance shell provides a software-packages utility that you can use to apply patches to the virtual appliance. You can log in to the appliance shell as root and use the software-packages utility to see the installed patches, stage new patches, and install new patches.
Patches are distributed in the form of an ISO image on the VMware Web site at https://my.vmware.com/web/vmware/downloads. VMware provides two ISO images that contain patches. One of the ISO images contains patches for all the VMware packages installed in the appliance. The other contains only third-party packages.
