When an applet requests a connection back to its originating host, the applet SecurityManager again performs a dynamic DNS lookup on the hostname. If the dynamic DNS lookup returns an IP address of some other computer, which can happen if someone is broadcasting bad DNS data, then the security manager allows the applet to connect to a machine it shouldn't be allowed to connect to.
Class loader can allow applets to load native code libraries.
Without an associated SecurityManager, the offending class can load native code libraries which can perform any operation. Inc. All Rights Reserved. Terms of Use . Privacy Policy .
