Apple has released the latest round of updates for its various products. They come with the usual security fixes, but also a new feature aimed at informing users about what information Apple-made apps collect about them and how that information is used.
The security fixes
Apple has plugged a bucketload of vulnerabilities in WebKit, the layout engine software component for rendering web pages in Safari, most of which may lead to arbitrary code execution, as well as a buffer overflow bug that could allow a malicious application to elevate privileges. These fixes are included in all of the updates.
