"The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-3121-1 advisory.

    It was discovered that the Hotspot component of OpenJDK did not properly check arguments of the
    System.arraycopy() function in certain cases. An attacker could use this to bypass Java sandbox
    restrictions. (CVE-2016-5582)

    It was discovered that OpenJDK did not restrict the set of algorithms used for Jar integrity verification.
    An attacker could use this to modify without detection the content of a JAR file, affecting system
    integrity. (CVE-2016-5542)

    It was discovered that the JMX component of OpenJDK did not sufficiently perform classloader consistency
    checks. An attacker could use this to bypass Java sandbox restrictions. (CVE-2016-5554)

    It was discovered that the Hotspot component of OpenJDK did not properly check received Java Debug Wire
    Protocol (JDWP) packets. An attacker could use this to send debugging commands to a Java application with
    debugging enabled. (CVE-2016-5573)

    It was discovered that OpenJDK did not properly handle HTTP proxy authentication. An attacker could use
    this to expose HTTPS server authentication credentials. (CVE-2016-5597)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
