    Oracle Java Critical Security Updates Released

    java

    Oracle released the scheduled critical security updates for its Java SE Runtime Environment software.  The update contains eight (8) new security fixes for Oracle Java SE. 
    Details for the CVE's addressed in the update are available here.

    Update

    If Java is still installed on your computer, it is recommended that this update be applied as soon as possible due to the threat posed by a successful attack.

    Download Information

    Download link:  Java SE 8u131

    Verify your version:  http://www.java.com/en/download/testjava.jsp

    Notes:
    • Minimally, UNcheck any pre-checked toolbar and/or software options presented with the update. They are not part of the software update and are completely optional.  Preferably, see the instructions below on how to handle "Unwanted Extras". 
    • Starting with Java SE 7 Update 21 in April 2013, all Java Applets and Web Start Applications should be signed with a trusted certificate.  It is not recommended to run untrusted/unsigned Certificates.  See How to protect your computer against dangerous Java Applets

    Critical Patch Updates

    For Oracle Java SE Critical Patch Updates, the next scheduled dates are as follows:
    • 18 July 2017
    • 17 October 2017
    • 16 January 2018
    • 17 April 2018

    Unwanted "Extras"

    Although most people do not need Java on their computer, there are some programs and games that require Java.  In the event you need to continue using Java, How-to Geek discovered a little-known and  unpublicized option in the Java Control Panel to suppress the offers for the pre-checked unwanted extras that Oracle has long included with the updates.  Although the Ask Toolbar has been removed, tha does not preclude the pre-checked option for some other unnecessary add-on.

    Do the following to suppress the sponsor offers:
    1. Launch the Windows Start menu
    2. Click on Programs
    3. Find the Java program listing
    4. Click Configure Java to launch the Java Control Panel
    5. Click the Advanced tab and go to the "Miscellaneous" section at the bottom.
    6. Check the box by the “Suppress sponsor offers when installing or updating Java” option and click OK.
    Java suppress sponsor offers

    Java Security Recommendations


    1)  In the Java Control Panel, at minimum, set the security to high.
    2)  Keep Java disabled until needed.  Uncheck the box "Enable Java content in the browser" in the Java Control Panel.

    3)  Instructions on removing older (and less secure) versions of Java can be found at http://java.com/en/download/faq/remove_olderversions.xml

    Microsoft Security Updates for April, 2017


    Today marks a red letter day for Microsoft updates.  In addition to security updates, sparking the most attention is the official release of the Windows 10 Creators Update (see the Windows Experience Blog post, What’s new in the Windows 10 Creators Update).

    Of lesser interest to many is the official "End of Life_ for Windows Vista.

    Also of note is the security guidance, Defense-in-Depth Update for Microsoft Office:
    "Microsoft has released an update for Microsoft Office that turns off, by default, the Encapsulated PostScript (EPS) Filter in Office as a defense-in-depth measure. Microsoft is aware of limited targeted attacks that could leverage an unpatched vulnerability in the EPS filter and is taking this action to help reduce customer risk until the security update is released.

    Microsoft strongly recommends against turning on the EPS filter at this time, however customers who need to turn on the EPS filter can reference KB Article 2479871."

    April Security Update Details:

    The April Microsoft updates address vulnerabilities in  Internet Explorer, Microsoft Edge, Microsoft Windows, Microsoft Office and Microsoft Office Services and Web Apps, Visual Studio for Mac, .NET Framework, Silverlight and Adobe Flash Player for Windows 8.1 and above.  Addressed in the updates are Remote Code Execution and Elevation of Privilege.  

    Microsoft has completed the change replacing security bulletins with the new Security Updates Guide.  The new guide includes the ability to view and search security vulnerability information in a single online database. The guide is described as a "portal" by the MSRC Team in Furthering our commitment to security updates. For more information about the updates released today, see https://portal.msrc.microsoft.com/en-us/security-guidance/summary.  Information about the update for Windows 10 is available at Windows 10 update history.
     

      Additional Update Notes

      • Adobe Flash Player -- For Windows Server 2012, Windows 8.1, Windows Server 2012 R2, Windows RT 8.1 and Windows 10, Adobe Flash Player is now a security bulletin rather than a security advisory and is included with the updates as identified above.
      • MSRT -- Microsoft released an updated version of the Microsoft Windows Malicious Software Removal Tool on Windows Update, Microsoft Update, Windows Server Update Services, and the Download Center. 
      • Reminder:  Windows Vista Reaching End of Live (EoL)
      • Windows 10 -- A summary of important product developments included in each update, with links to more details is available at Windows 10 Update History. The page will be regularly refreshed, as new updates are released.
