Sun Java Runtime Environment Mutable InetAddress Socket Policy Violation Vulnerability

This vulnerability allows remote attackers to violate security policies on vulnerable installations of Sun Java Runtime. 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.
