CVE-2016-3427Oracle Java — the management extensions left open

An unspecified flaw in the management extensions (JMX) of Oracle Java lets a remote attacker reach confidentiality, integrity and availability alike. Java 6u113, 7u99 and 8u77, the embedded build and JRockit are named.

YOUR NEXT MOVE

Apply Oracle's April 2016 Java update, and close the management extension ports — an application that never exposes them is out of reach of this one.
