Java (1.7.0_13) update fixes 50 security vulnerabilities

Oracle has released another update of Java (1.7.0_13). For those who need Java, it is strongly advised to update as soon as you can.
You can download the latest version here: http://www.java.com
Those running Windows can either chose to turn on automatic updates to be sure to always have the latest version: http://www.java.com/en/download/help/java_update.xml
Remember to delete any previous installed Java versions from your system when you update. See http://java.com/en/download/faq/remove_olderversions.xml for assistance with this.

We’d like to remind everyone about these three points though:
If you don’t need Java at all – uninstall it: http://www.java.com/en/download/uninstall.jsp www.java.com/en/download/help/mac_uninstall_java.xml

If you need Java for stand-alone applications such as Minecraft, disable Java in your browsers: http://www.java.com/en/download/help/disable_browser.xml

If you need Java in your browser, disable it in your Primary browser and keep it active in a secondary browser. This way, you will only have Java activated in the secondary browser when you have the need to visit your banking site or such:

If you need it for stand-alone applications such as Minecraft, disable Java in browsers
In Firefox, select “Tools” from the main menu, then “Add-ons,” then click the “Disable” button next to any Java plug-ins.
In Safari, click “Safari” in the main menu bar, then “Preferences,” then select the “Security” tab and uncheck the button next to “Enable Java.”
In Chrome, type or copy “Chrome://Plugins” into your browser’s address bar, then click the “Disable” button below any Java plug-ins.
In Internet Explorer, follow these instructions for disabling Java in all browsers via the Control Panel. There is no way to completely disable Java specifically in IE.
