"The version of Oracle Enterprise Manager Cloud Control installed on
the remote host is affected by multiple vulnerabilities in the
Enterprise Manager Base Platform component :

  - A flaw exists in the Bouncy Castle Java library due to
    improper validation of a point within the elliptic
    curve. An unauthenticated, remote attacker can exploit
    this to obtain private keys by using a series of
    specially crafted elliptic curve Diffie-Hellman (ECDH)
    key exchanges, also known as an 'invalid curve attack.'
    (CVE-2015-7940)

  - A flaw exists in Apache MyFaces Trinidad, specifically
    in the CoreResponseStateManager component, due to the
    ObjectInputStream and ObjectOutputStream strings being
    used directly without securely deserializing Java input.
    An unauthenticated, remote attacker can exploit this,
    via a deserialization attack using a crafted serialized
    view state string, to have an unspecified impact that
    may include the execution of arbitrary code.
    (CVE-2016-5019)

Note that the product was formerly known as Enterprise Manager Grid
Control.");
