RMI implementation in OpenJDK uses property java.rmi.server.useCodebaseOnly, which controls whether automatic loading of classes from other sources than local CLASSPATH and location specified in the java.rmi.server.codebase property is permitted. This property previously defaulted to false, allowing dynamic class downloading. This could allow an attacker to make RMI server or registry to execute arbitrary untrusted code. It was demonstrated that this can be used in combination with another Java sandbox bypass flaw to execute code in the remote rmiregistry or GlassFish Server: <a href="http://seclists.org/fulldisclosure/2013/Feb/18">http://seclists.org/fulldisclosure/2013/Feb/18</a> <a href="http://www.security-explorations.com/en/SE-2012-01-details.html">http://www.security-explorations.com/en/SE-2012-01-details.html</a> <a href="http://www.security-explorations.com/materials/se-2012-01-rmi.zip">http://www.security-explorations.com/materials/se-2012-01-rmi.zip</a> This update changes the default value of the java.rmi.server.useCodebaseOnly property to true.
