Current Software Versions

Adobe Flash

Adobe Reader DC 2015.023.20053

Dropbox 17.4.33 [Citadel warns against relying on security of Dropbox or other cloud-based file exchange systems. We recommend files containing sensitive information be independently encrypted with a program like Axcrypt; 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 50.1.0 [Windows]

Google Chrome 55.0.2883.87

Internet Explorer 11.0.9600.18538

Java SE 8 Update 121 [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, Citadel recommends 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 39.14986.0.0

QuickTime 7.7.9 [Citadel recommends removing QuickTime. On April 14, 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 10.0.2 [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 workstation 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 cyber security 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.
