This morning, Apple pushed the official version of iOS 16.6.1, which was released one and a half months after the last official version was released. The update version number is 20G81. Users who plan to upgrade can directly upgrade in the software update.

Judging from the update upgrades given by Apple, this update mainly provides important security fixes and is recommended for all users to install.

The official version of iOS 16.6.1 is a minor update based on iOS 16.6, mainly focusing on fixing bugs and no new features are added.

Two system bugs were mainly fixed. One was related to ImageIO, which is Apple's framework that allows applications to read and write most image file formats and access image metadata. The vulnerability may cause processing maliciously crafted images to cause arbitrary code execution. Apple said it has solved the buffer overflow problem by improving memory handling.

The other affects the Apple Wallet application. The existence of this vulnerability may allow maliciously crafted attachments to cause arbitrary code execution. Apple has solved the verification problem by improving the logic.

In addition, Apple also released the official version updates of macOS 13.5.2 and watchOS 9.6.2, which also brought security fixes.
