service vulnerabilities :

    - A denial of service vulnerability exists due to a NULL

      (NFC) traffic. An unauthenticated, remote attacker can
      exploit this by intercepting and modifying the traffic
      between the ESX / ESXi host and the client.
      (CVE-2014-1207)

    - A flaw exists due to improper handling of invalid
      ports. An unauthenticated attacker on an adjacent
      network can exploit this to cause VMX processing to
      fail, resulting in a partial denial of service.
