Oracle Java Critical Security Update

java

Oracle released the scheduled critical security updates for its Java SE Runtime Environment software.

The update contains seventeen (17) new security fixes for Oracle Java SE.  Sixteen (16) of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials. 

Details for the CVE's addressed in the update are available here.

Known Issue:

Java Installation will fail for non-admin users with UAC off:
The Java installation on Windows will fail without warning or prompting, for non-admin users with User Access Control (UAC) disabled. The installer will leave a directory, jds<number>.tmp, in the %TEMP% directory.
JDK-8161460 (not public)

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 8u121

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 April 2017
  • 18 July 2017 
  • 17 October 2017
  • 16 January 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

Windows XP

For information on Java support for Windows XP, organizations and individuals who must continue using Windows XP and have Java installed are referred to the Oracle blog post, The future of Java on Windows XP (Henrik on Java).

Java Security Recommendations

For those people who have desktop applications that require Java and cannot uninstall it, Java can now be disabled in Internet Explorer.  See Microsoft Fix it to Disable Java in Internet Explorer.

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.

      Adobe Flash Player and AIR Critical Security Updates Released

      Adobe Flashplayer

      Adobe has released Version 24.0.0.194 of Adobe Flash Player for Microsoft Windows, Macintosh, Chrome and Linux.

      These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system. 

      Release date: January 10, 2017
      Vulnerability identifier: APSB17-02
      CVE number: CVE-2017-2925, CVE-2017-2926, CVE-2017-2927, CVE-2017-2928, CVE-2017-2930, CVE-2017-2931, CVE-2017-2932, CVE-2017-2933, CVE-2017-2934, CVE-2017-2935, CVE-2017-2936, CVE-2017-2937, CVE-2017-2938
      Platform: Windows, Macintosh, Linux and Chrome OS

      Warning:  Although Adobe suggests downloading the update from the Adobe Flash Player Download Center, that link includes a pre-checked option to install unnecessary extras, such as McAfee Scan Plus or Google Drive.  If you use the download center, uncheck any unnecessary extras.

      Edit Note:  The old direct download links for NPAPI (Firefox, Pale Moon) and ActiveX Plugin are not currently working.  In addition, Opera/Chromium-based browsers now use the Pepper/PPAPI plugin. 

      The updated links are below.  The local offline installers are also available at the bottom of this page: https://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html

      If you use the download center, uncheck any unnecessary extras.
        Notes:
        • If you use the Adobe Flash Player Download Center, be careful to uncheck any optional downloads that you do not want.  Any pre-checked option is not needed for the Flash Player update.
        • Uncheck any toolbar offered with Adobe products if not wanted.
        • If you use alternate browsers, it is necessary to install the update for both Internet Explorer as well as the update for alternate browsers.
        • The separate 32-bit and 64-bit uninstallers have been replaced with a single uninstaller.

        Verify Installation

        To verify the Adobe Flash Player version number installed on your computer, go to the About Flash Player page, or right-click on content running in Flash Player and select "About Adobe Flash Player" from the menu. 

        Do this for each browser installed on your computer.

        To verify the version of Adobe Flash Player for Android, go to Settings > Applications > Manage Applications > Adobe Flash Player x.x.
