Apple has started rolling out Security Response Update (c) for supported devices running iOS 16.5.1, iPadOS 16.5.1, and macOS Ventura 13.4.1. These updates come two days after the release of Security Response Update (a) for iOS 16.5.1, iPadOS 16.5.1, and macOS Ventura 13.4.1 which addressed an actively exploited WebKit vulnerability. However, the update was shortly pulled by Apple as it prevented some websites from displaying properly after installation. Today, Apple has again re-released the update (c) to now also include a fix for the website issue.
According to Apple, the recent security response updates fix a WebKit vulnerability: This vulnerability has the potential to process maliciously crafted web content, which may lead to arbitrary code execution. Apple has improved checks to address this actively exploited vulnerability.
Discovered & Reported by: An anonymous researcher.
You can expect the size of this update to be around 2-3 MB on your iPhone & iPad, and around 130-150MB on your Mac.
To update your supported iPhone, iPad, and Mac, navigate over to Settings>General>Software Update and you will see the new Rapid Security Response update. In case you do not see the update, you can restart your device and make sure that it is connected to the internet. It is highly recommended to update your iPhone, iPad, and Mac for the best security.
