It"s that time again, the time to check for updates on every single thing that you own that has an Apple logo on it, as iOS 10.3.2, macOS 10.12.5 Sierra, watchOS 3.2.2, and tvOS 10.2.1 are now available to everyone.
To be clear, these updates are available to all devices that were eligible for their predecessors, despite some publications that said otherwise. The original iOS 10.3.2 beta didn"t include images for 32-bit devices (4th-gen iPad, iPhone 5, iPhone 5c), but all of the following builds did, including the public one.
As the version numbers indicate, there are no new front-facing features in these updates; instead, they focus on bug fixes, stability improvements, and security. In fact, the lists of security fixes in these updates are quite long.
While iOS 10.3.1 listed just one security fix, 10.3.2 lists 23. They include improvements for AVEVideoEncoder, CoreAudio, iBooks, IOSurface, Kernel, Notifications, Safari, SQLite, TextInput, WebKit, and WebKit Web Inspector. You can find the full list of vulnerabilities that were fixed here.
macOS 10.12.5 Sierra contains 30 security fixes. Some of them are similar, such as separate graphics drivers for Nvidia and Intel, both of which fix an issue where an application can gain kernel privileges. You can find the full list here.
watchOS 3.2.2 has just 10 fixes, including AVEVideoEncoder, CoreAudio, IOSurface, Kernel, SQLite, TextInput, and WebKit. Here"s the full list.
Finally, tvOS 10.2.1 fixes 14 different vulnerabilities having to do with AVEVideoEncoder, CoreAudio, IOSurface, Kernel, SQLite, TextInput, WebKit, and WebKit Web Inspector. Obviously, it"s recommended that you install all of these updates as soon as possible.
