"The remote VMware ESXi 5.1 host is affected by the following
vulnerabilities :

  - A denial of service vulnerability exists in the bundled
    OpenSSL library that is triggered when handling OCSP
    response verification. A remote attacker can exploit
    this to crash the program. (CVE-2013-0166)

  - An error exists related to the SSL/TLS/DTLS protocols,
    CBC mode encryption and response time. An attacker
    can obtain plaintext contents of encrypted traffic via
    timing attacks. (CVE-2013-0169)

  - An error exists in the libxml2 library related to the
    expansion of XML internal entities that could allow
    denial of service attacks. (CVE-2013-0338)

  - A NULL pointer dereference flaw exists in the handling
    of Network File Copy (NFC) traffic. An attacker can
    exploit this by intercepting and modifying NFC traffic,
    to cause a denial of service condition. (CVE-2014-1207)

  - A denial of service vulnerability exists in the handling
    of invalid ports that could allow a guest user to crash
    the VMX process. (CVE-2014-1208)");
