"The remote host is using an unmanaged version of Sun Java Runtime
Environment that has vulnerabilities in its Java Runtime Plug-in, a web
browser add-on used to display Java applets.

The JRE Plug-in security can be bypassed by tricking a user into viewing
a maliciously crafted web page.

Additionally, a denial of service vulnerability is present in this
version of the JVM.  This issue is triggered by viewing an applet that
misuses the serialization API.");
