Apple Releases Multiple Security Updates for Multiple Products

Apple released several security updates this week, addressing a number of vulnerabilities across its products ranging from Mac OS X to its Safari Web browser and iOS that runs iPhones, iPads and iPods.

Several of the updates addressed an incident surrounding the fraudulent SSL certificates recently issued by a Comodo affiliate registration authority, which could allow a man-in-the-middle attack redirecting connections and intercepting user credentials or other sensitive information.

A Summary of the security updates released by Apple are below:
