User interaction is required to exploit this vulnerability in that the target must run a malicious applet.
The specific flaw allows malicious applets to connect to network addresses other than the originating applet and client IPs. A handcrafted applet can override compile time checks to prevent compilation of a mutable InetAddress subclass. This results in the ability to circumvent the Applet SecurityManager restictions.
Sun Microsystems has issued an update to correct this vulnerability. More details can be found at:
