Description Marc Schoenefeld 2009-07-20 14:13:58 UTC 
public class TestApplet extends Applet {
        public static void main(String[] a) {

        }

        public void init() {
                JSObject i = new JSObject(Integer.MAX_VALUE);
                JSObject j = new JSObject(Long.MAX_VALUE);
                i.getMember("Willi");
                j.getMember("Willi");
        }
}

segfaults the browser. The parameter to JSObject is interpreted as memory location, and a getMember call makes access to it. Giving these functionality to untrusted 

Affects: 
F10, F11

Proposed fix: 
Remove public visibility of JSObject(long) and JSObject(int)
