Oracle has released a security update to Java that includes fixes for several security vulnerabilities. The updated version is JDK/JRE 7 Update 51. Updates are available for Java 7 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
Please note that this release of Java will not run unsigned applets, so if you have been receiving alerts from previous versions of Java saying that a future release will not run the applet you are using, this is the release. If you received the Java applet from a vendor, be sure to contact the vendor to find out what they are doing to resolve this issue.
