Oracle Java Critical Security Update

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

This is a Critical Patch Update that contains 20 fixes for Java, the most severe having a rating of 10.0 relating to the vulnerability described in CVE-2014-4227 (currently listed as "reserved"). 

According to the Oracle Blog, seven (7) other Java SE client vulnerabilities have a CVSS Base Score of 9.3.  Although this means that a complete compromise of the client is possible, according to Oracle, aaccess complexity to exploit these vulnerabilities is “medium.”)   Additional details about the update are available in the Java Release Notes, referenced below.

Windows XP

There has been a lot of recent controversy regarding Java updates for Windows XP.  While Windows XP has reached end of life, Java 7 will continue to be updated until April, 2015.

Thus, organizations and individuals who must continue using Windows XP and have Java installed can also continue getting updates for Java 7.  It is noted, however, that if an issue arises that is specific to Windows XP, Oracle is not required to and also may not be able to create a patch.  For additional information, refer to the Oracle blog post, The future of Java on Windows XP (Henrik on Java).

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.

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.

3)  If you use Firefox, install NoScript and only allow Java on those sites where it is required.
