CVE-2018-2800: Medium severity Oracle JDK vulnerability
It was discovered that the RMI component of OpenJDK enabled HTTP transport for RMI servers by default. This could possibly expose RMI services to attackers who can not connect to them directly by attacking web browsers of users able to directly connect to the services.
The fix for this issue disables the use of RMI HTTP transport by default. System properly java.rmi.server.disableIncomingHttp (with the default value of "true") can be used to enable HTTP transport.
