3. Problem Description

   a. VMware ESXi and ESX NFC Protocol Unhandled Exception  

      VMware ESXi and ESX contain a vulnerability in the handling of
      the Network File Copy (NFC) protocol. To exploit this
      vulnerability, an attacker must intercept and modify the NFC
      traffic between ESXi/ESX and the client.  Exploitation of the
      issue may lead to a Denial of Service.

      To reduce the likelihood of exploitation, vSphere components should
      be deployed on an isolated management network

      VMware would like to thank Alex Chapman of Context Information
      Security for reporting this issue to us.

      The Common Vulnerabilities and Exposures project (
