The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2998 advisory.

    The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java     Software Development Kit.

    Security Fix(es):

    * Multiple flaws were discovered in the RMI and Hotspot components in OpenJDK. An untrusted Java     application or applet could use these flaws to completely bypass Java sandbox restrictions.
    (CVE-2017-10285, CVE-2017-10346)

    * It was discovered that the Kerberos client implementation in the Libraries component of OpenJDK used the     sname field from the plain text part rather than encrypted part of the KDC reply message. A man-in-the-     middle attacker could possibly use this flaw to impersonate Kerberos services to Java applications acting     as Kerberos clients. (CVE-2017-10388)

    * It was discovered that the Security component of OpenJDK generated weak password-based encryption keys     used to protect private keys stored in key stores. This made it easier to perform password guessing     attacks to decrypt stored keys if an attacker could gain access to a key store. (CVE-2017-10356)

    * A flaw was found in the Smart Card IO component in OpenJDK. An untrusted Java application or applet     could use this flaw to bypass certain Java sandbox restrictions. (CVE-2017-10274)

    * It was found that the FtpClient implementation in the Networking component of OpenJDK did not set     connect and read timeouts by default. A malicious FTP server or a man-in-the-middle attacker could use     this flaw to block execution of a Java application connecting to an FTP server. (CVE-2017-10355)

    * It was found that the HttpURLConnection and HttpsURLConnection classes in the Networking component of     OpenJDK failed to check for newline characters embedded in URLs. An attacker able to make a Java     application perform an HTTP request using an attacker provided URL could possibly inject additional     headers into the request. (CVE-2017-10295)

    * It was discovered that multiple classes in the JAXP, Serialization, Libraries, and JAX-WS components of     OpenJDK did not limit the amount of memory allocated when creating object instances from the serialized     form. A specially-crafted input could cause a Java application to use an excessive amount of memory when     deserialized. (CVE-2017-10349, CVE-2017-10357, CVE-2017-10347, CVE-2017-10281, CVE-2017-10345,     CVE-2017-10348, CVE-2017-10350)

    Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via     Java applets could have been exploited without user interaction if a user visited a malicious website.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
