Current Software Versions
Adobe Flash Player 126.96.36.1993 [Flash is a major source of cyber criminal exploits and is not needed for most internet browsing. Doing without Flash—or at least without Flash turned on all the time—makes good security sense, and it isn’t as difficult as you might think: See Brian Krebs’ post, A Month Without Adobe Flash Player, for tips on how to minimize the risks of having Flash installed.]
Adobe Acrobat Reader DC 19.021.20058
Dropbox 88.4.172 [Citadel warns against relying on security of Dropbox or other cloud-based file exchange systems. We recommend files containing sensitive information be independently encrypted; encryption keys be at least 15 characters long; and the master Dropbox [or other] password be at least 15 characters long and different from other passwords.]
Firefox 72.0.1 [Windows]
Google Chrome Version 79.0.3945.117 (Official Build)
Java SE 8 Update 231 [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 or application that requires Java, Citadel recommends using a two-browser approach to minimize risk. Unplug Java from the browser you use for everyday surfing and leave it plugged in to a second browser that you only use for sites that require Java. And if you have a specific use or need for Java, make sure you have the latest version.]
Microsoft Edge 44.18362.449.0
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.]
Safari 13.0.1 [Mac OS X Mavericks, Yosemite, El Capitan]

If you are responsible for the security of your computer, Citadel’s Weekend Vulnerability and Patch Report is for you. We strongly urge you to take action to keep your system(s) patched and updated.
If someone else is responsible for the security of your computer, forward our Weekend Vulnerability and Patch Report to them and follow up to make sure your computer has been patched and updated.
Vulnerability management is a key element of cybersecurity management. Cyber criminals take over user computers by writing computer programs that “exploit” vulnerabilities in operating systems (Windows, Apple OS, etc) and application programs (Adobe Acrobat, Office, Flash, Java, etc). When software companies find a vulnerability, they usually issue an update patch to fix the code running in their customer’s computers.
Citadel publishes our Weekend Vulnerability and Patch Report to alert readers to some of the week’s important updates and vulnerabilities. Our focus is on software typically found in the small or home office (SOHO) or that users are likely to have on their home computer. The report is not intended to be a thorough listing of updates and vulnerabilities.
