"The remote host is running a version of McAfee Email Gateway (MEG)
that is affected by the multiple vulnerabilities related to the
included OpenSSL library :

  - An error exists in the function 'ssl3_read_bytes' that
    can allow data to be injected into other sessions or
    allow denial of service attacks. Note that this issue is
    exploitable only 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
    can 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 can lead to execution of
    arbitrary code. Note that 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
    can allow a NULL pointer to be dereferenced leading
    to denial of service attacks. Note that this issue is
    exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is
    enabled. (CVE-2014-0198)

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

  - An unspecified error exists that can 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
    cipher suites that can allow denial of service attacks.
    Note that this issue only affects OpenSSL TLS clients.
