"The version of Oracle Enterprise Manager Cloud Control installed on
the remote host is missing a security patch. It is, therefore,
affected by multiple vulnerabilities:

  - A carry propagating bug exists in the x86_64 Montgomery
    squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before
    1.1.0g. No EC algorithms are affected. Analysis suggests that
    attacks against RSA and DSA as a result of this defect would
    be very difficult to perform and are not believed likely.
    Attacks against DH are considered just feasible (although very
    difficult) because most of the work necessary to deduce
    information about a private key may be performed offline. The
    amount of resources required for such an attack would be very
    significant and likely only accessible to a limited number of
    attackers. An attacker would additionally need online access
    to an unpatched system using the target private key in a
    scenario with persistent DH parameters and a private key that
    is shared between multiple clients. This issue affects only
    processors that support the BMI1, BMI2 and ADX extensions like
    Intel Broadwell (5th generation) and later or AMD Ryzen.
    (CVE-2017-3736)

  - A flaw exists in parsing routine of IPAddressFamily extension
    in an X.509 certificate, it is possible to do a one-byte
    overread. An attacker can exploit this issue to display an
    incorrect text of the certificate. This bug has been present
    since 2006 and is present in all versions of OpenSSL before
    1.0.2m and 1.1.0g. (CVE-2017-3735)");
