The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:0049 advisory.

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

    An out-of-bounds write flaw was found in the JPEG image format decoder in     the AWT component in OpenJDK. A specially crafted JPEG image could cause     a Java application to crash or, possibly execute arbitrary code. An     untrusted Java application or applet could use this flaw to bypass Java     sandbox restrictions. (CVE-2016-0483)

    An integer signedness issue was found in the font parsing code in the 2D     component in OpenJDK. A specially crafted font file could possibly cause     the Java Virtual Machine to execute arbitrary code, allowing an untrusted     Java application or applet to bypass Java sandbox restrictions.
    (CVE-2016-0494)

    It was discovered that the password-based encryption (PBE) implementation     in the Libraries component in OpenJDK used an incorrect key length. This     could, in certain cases, lead to generation of keys that were weaker than     expected. (CVE-2016-0475)

    It was discovered that the JAXP component in OpenJDK did not properly     enforce the totalEntitySizeLimit limit. An attacker able to make a Java     application process a specially crafted XML file could use this flaw to     make the application consume an excessive amount of memory. (CVE-2016-0466)

    A flaw was found in the way TLS 1.2 could use the MD5 hash function for     signing ServerKeyExchange and Client Authentication packets during a TLS     handshake. A man-in-the-middle attacker able to force a TLS connection to     use the MD5 hash function could use this flaw to conduct collision attacks     to impersonate a TLS server or an authenticated TLS client. (CVE-2015-7575)

    Multiple flaws were discovered in the Networking and JMX components in     OpenJDK. An untrusted Java application or applet could use these flaws to     bypass certain Java sandbox restrictions. (CVE-2016-0402, CVE-2016-0448)

    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.

    Note: This update also disallows the use of the MD5 hash algorithm in the     certification path processing. The use of MD5 can be re-enabled by removing     MD5 from the jdk.certpath.disabledAlgorithms security property defined in     the java.security file.

    All users of java-1.8.0-openjdk are advised to upgrade to these updated     packages, which resolve these issues. All running instances of OpenJDK Java     must be restarted for the update to take effect.

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.
