Netscape Communicator URL Read Vulnerability
A flaw in Netscape Communicator's implementation of
Java allows malicious applets to read any resource
reachable via a URL from the local machine by using the
netscape.net.URLConnection and
netscape.net.URLInputSteam classes. This allows
malicious applets to read local files as well as download
data from hosts that would otherwise be protected
by a firewall. Here's more information and a workaround.
