"According to its version number, the Sun Java Runtime Environment
(JRE) installed on the remote host reportedly contains an issue in
'jpiexp32.dll' that can lead to a NULL pointer exception when an HTML
object references a Java applet but does not define the 'name'
attribute.  If a remote attacker can trick a user on the affected host
into visiting a specially crafted web page, this issue could be 
leveraged to cause the JRE and Internet Explorer to crash.");
