  script_tag(name:"insight", value:"a. VMware ESXi and ESX NFC NULL pointer dereference

  VMware ESXi and ESX contain a NULL pointer dereference in the handling of the Network File Copy
  (NFC) traffic. 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.

  b. VMware VMX process denial of service vulnerability

  Due to a flaw in the handling of invalid ports, it is possible to cause the VMX process to fail.
  This vulnerability may allow a guest user to affect the VMX process resulting in a partial denial
  of service on the host.");
