"The remote host is running a version of McAfee Web Gateway (MWG) that
is affected by multiple vulnerabilities due to flaws 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 related to the implementation of the
    Elliptic Curve Digital Signature Algorithm (ECDSA) that
    could allow nonce disclosure via the 'FLUSH+RELOAD'
    cache side-channel attack. (CVE-2014-0076)

  - A buffer overflow error exists related to invalid DTLS
    fragment handling that could lead to execution of
    arbitrary code. Note this issue only affects OpenSSL
    when used as a DTLS client or server. (CVE-2014-0195)

  - 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 error exists related to DTLS handshake handling that
    could lead to denial of service attacks. Note this
    issue only affects OpenSSL when used as a DTLS client.
    (CVE-2014-0221)

  - 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)");
