Java SE 8 Update 131 [Citadel recommends removing or disabling Java from your browser. Java is a major source of cyber criminal exploits. It is not needed for most internet browsing. If you have a particular web site that requires Java, Citadelrecommends using a two-browser approach to minimize risk. If you normally browse the Web with Firefox, for example, disable the Java plugin in Firefox and use an alternative browser — such as Chrome, IE9, Safari, etc — with Java enabled to browse only the sites that require it.]
Microsoft Edge 40.15063.0.0
QuickTime 7.7.9 [Citadel recommends removing QuickTime. On April 14, 2016 US-CERT advised Microsoft Windows users to remove QuickTime. This followed a report in ars technica that Apple has no plans to update the Windows app despite at least two reliable QuickTime vulnerabilities that threaten Windows users who still have the program installed.]
