Oracle has released a security update to Java that includes fixes for several security vulnerabilities. The updated versions are JDK/JRE 8 Update 45 and 7 Update 79. Updates are available for Java 7 and Java 8 on Windows, Solaris, Linux, and Mac OS. Be sure to update your Java installation(s) as soon as possible.
This release is available for both server and workstation installations of Java. Java can be updated via the included Java Updater or at http://java.com/en/download/index.jsp
* NOTE: Java 7u79 is the LAST release of Java 7. If you are still using Java 7, please upgrade to Java 8 now as there will be no more Java 7 releases. *
Continuing to use a vulnerable version of Java, especially in a browser, is a surefire way to end up with a compromised system.
At this time there isn’t any more information on what was fixed in the new release of Java.
