BackgroundWhen used in a web page, Java references properties of the window.navigator object as it starts up in Firefox or SeaMonkey.
ProblemIf a web page replaces the navigator object before starting Java, then the page could cause the browser to crash in a way that allows arbitrary command execution.
ResolutionUpgrade to Firefox 188.8.131.52 or higher or SeaMonkey 1.0.3 or higher.
LimitationsExploit works on Firefox 184.108.40.206 and requires a user to click on the Exploit button. The Java plug-in must be installed in order for the exploit to succeed. Firefox's automatic update feature must be disabled in order for the exploit to succeed.
