User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The specific flaw is due to insufficient defenses against system clipboard hijacking. When in focus, a handle to the system clipboard can be retrieved without user interaction by a malicious component. The clipboard can then be arbitrarily read from or written to. By writing a TransferableProxy object to the system clipboard and then forcing a paste action, arbitrary code can be executed under the context of the user invoking the JRE.
