According to its self-reported version, the MySQL Enterprise Monitor application running on the remote host is 3.3.x prior to 3.3.1.1112.
It is, therefore, affected by multiple vulnerabilities in the bundled version of OpenSSL :

  - Multiple integer overflow conditions exist in s3_srvr.c,     ssl_sess.c, and t1_lib.c due to improper use of pointer     arithmetic for heap-buffer boundary checks. An     unauthenticated, remote attacker can exploit this to     cause a denial of service. (CVE-2016-2177)

  - An information disclosure vulnerability exists in the     dsa_sign_setup() function in dsa_ossl.c due to a failure     to properly ensure the use of constant-time operations.
    An unauthenticated, remote attacker can exploit this,     via a timing side-channel attack, to disclose DSA key     information. (CVE-2016-2178)

  - A denial of service vulnerability exists in the DTLS     implementation due to a failure to properly restrict the     lifetime of queue entries associated with unused     out-of-order messages. An unauthenticated, remote     attacker can exploit this, by maintaining multiple     crafted DTLS sessions simultaneously, to exhaust memory.
    (CVE-2016-2179)

  - An out-of-bounds read error exists in the X.509 Public     Key Infrastructure Time-Stamp Protocol (TSP)     implementation. An unauthenticated, remote attacker can     exploit this, via a crafted time-stamp file that is     mishandled by the 'openssl ts' command, to cause     denial of service or to disclose sensitive information.
    (CVE-2016-2180)

  - A denial of service vulnerability exists in the     Anti-Replay feature in the DTLS implementation due to     improper handling of epoch sequence numbers in records.
    An unauthenticated, remote attacker can exploit this,     via spoofed DTLS records, to cause legitimate packets to     be dropped. (CVE-2016-2181)

  - An overflow condition exists in the BN_bn2dec() function     in bn_print.c due to improper validation of     user-supplied input when handling BIGNUM values. An     unauthenticated, remote attacker can exploit this to     crash the process. (CVE-2016-2182)

  - A vulnerability exists, known as SWEET32, in the 3DES     and Blowfish algorithms due to the use of weak 64-bit     block ciphers by default. A man-in-the-middle attacker     who has sufficient resources can exploit this     vulnerability, via a 'birthday' attack, to detect a     collision that leaks the XOR between the fixed secret     and a known plaintext, allowing the disclosure of the     secret text, such as secure HTTPS cookies, and possibly     resulting in the hijacking of an authenticated session.
    (CVE-2016-2183)

  - A flaw exists in the tls_decrypt_ticket() function in     t1_lib.c due to improper handling of ticket HMAC     digests. An unauthenticated, remote attacker can exploit     this, via a ticket that is too short, to crash the     process, resulting in a denial of service.
    (CVE-2016-6302)

  - An integer overflow condition exists in the     MDC2_Update() function in mdc2dgst.c due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or possibly the execution of arbitrary code.
    (CVE-2016-6303)

  - A denial of service vulnerability exists in the     ssl_parse_clienthello_tlsext() function in t1_lib.c due     to improper handling of overly large OCSP Status Request     extensions from clients. An unauthenticated, remote     attacker can exploit this, via large OCSP Status Request     extensions, to exhaust memory resources. (CVE-2016-6304)

  - An out-of-bounds read error exists in the certificate     parser that allows an unauthenticated, remote attacker     to cause a denial of service via crafted certificate     operations. (CVE-2016-6306)

According to the versions of the openssl098e package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The DTLS implementation in OpenSSL before 1.1.0 does     not properly restrict the lifetime of queue entries     associated with unused out-of-order messages, which     allows remote attackers to cause a denial of service     (memory consumption) by maintaining many crafted DTLS     sessions simultaneously, related to d1_lib.c,     statem_dtls.c, statem_lib.c, and     statem_srvr.c.(CVE-2016-2179)

  - OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC     3779 support is enabled, allows remote attackers to     cause a denial of service (assertion failure) via an     X.509 certificate containing certificate-extension data     associated with (1) IP address blocks or (2) Autonomous     System (AS) identifiers.(CVE-2011-4577)

  - Memory leak in the dtls1_buffer_record function in     d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1     before 1.0.1k allows remote attackers to cause a denial     of service (memory consumption) by sending many     duplicate records for the next epoch, leading to     failure of replay detection.(CVE-2015-0206)

  - The ephemeral ECDH ciphersuite functionality in OpenSSL     0.9.8 through 0.9.8r and 1.0.x before 1.0.0e does not     ensure thread safety during processing of handshake     messages from clients, which allows remote attackers to     cause a denial of service (daemon crash) via     out-of-order messages that violate the TLS     protocol.(CVE-2011-3210)

  - The X509_NAME_oneline function in     crypto/x509/x509_obj.c in OpenSSL before 1.0.1t and     1.0.2 before 1.0.2h allows remote attackers to obtain     sensitive information from process stack memory or     cause a denial of service (buffer over-read) via     crafted EBCDIC ASN.1 data.(CVE-2016-2176)

  - The ssl3_get_cert_verify function in s3_srvr.c in     OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k     accepts client authentication with a Diffie-Hellman     (DH) certificate without requiring a CertificateVerify     message, which allows remote attackers to obtain access     without knowledge of a private key via crafted TLS     Handshake Protocol traffic to a server that recognizes     a Certification Authority with DH     support.(CVE-2015-0205)

  - The ssl3_get_key_exchange function in s3_clnt.c in     OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1     before 1.0.1k allows remote SSL servers to conduct     ECDHE-to-ECDH downgrade attacks and trigger a loss of     forward secrecy by omitting the ServerKeyExchange     message.(CVE-2014-3572)

  - Memory leak in d1_both.c in the DTLS implementation in     OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and     1.0.1 before 1.0.1i allows remote attackers to cause a     denial of service (memory consumption) via zero-length     DTLS fragments that trigger improper handling of the     return value of a certain insert     function.(CVE-2014-3507)

  - The ssl23_get_client_hello function in s23_srvr.c in     OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle     attackers to force the use of TLS 1.0 by triggering     ClientHello message fragmentation in communication     between a client and server that both support later TLS     versions, related to a 'protocol downgrade'     issue.(CVE-2014-3511)

  - The ssl3_send_client_key_exchange function in s3_clnt.c     in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and     1.0.1 before 1.0.1h, when an anonymous ECDH cipher     suite is used, allows remote attackers to cause a     denial of service (NULL pointer dereference and client     crash) by triggering a NULL certificate     value.(CVE-2014-3470)
