CVE-2015-4733

First published: Sun Jul 12 2015(Updated: )

It was discovered that the RemoteObjectInvocationHandler class in the RMI component of OpenJDK did not prevent calls to the finalize() method. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions. The patch prevents calls of the finalize() method. It also makes it possible to re-enable support for calling the method via the sun.rmi.server.invocationhandler.allowFinalizeInvocation system property.
