[原文]Java in Netscape 4.5 does not properly restrict applets from connecting to other hosts besides the one from which the applet was loaded, which violates the Java security model and could allow remote attackers to conduct unauthorized activities.
Netscape contains a flaw that may allow a malicious user to bypass authentication. The issue is triggered when a Java applet is loaded under Netscape, which will allow any host to connect to the machine running the applet. It is possible that the flaw may allow a remote attacker to gain unauthorized access to the system, resulting in a loss of integrity.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: Disable Java runtime in the Netscape browser.
