"The remote VMware ESXi host is version 5.1 prior to build 1900470. It
is, therefore, affected by the following vulnerabilities in the
OpenSSL library :

  - An error exists in the function 'ssl3_read_bytes'
    that could allow data to be injected into other
    sessions or allow denial of service attacks. Note
    this issue is only exploitable if
    'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2010-5298)

  - An error exists in the function 'do_ssl3_write' that
    could allow a NULL pointer to be dereferenced leading
    to denial of service attacks. Note this issue is
    exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is
    enabled. (CVE-2014-0198)

  - An unspecified error exists that could allow an
    attacker to cause usage of weak keying material
    leading to simplified man-in-the-middle attacks.
    (CVE-2014-0224)

  - An unspecified error exists related to anonymous ECDH
    ciphersuites that could allow denial of service
    attacks. Note this issue only affects OpenSSL TLS
    clients. (CVE-2014-3470)");
