Apple patches two zero-day threats in iOS 16.6, macOS 13.5 and iPadOS 16.6

Apple has released iOS 16.6, macOS 13.5 and iPadOS 16.6. The updates patch a number of security issues, including two actively exploited vulnerabilities.

You may be aware that Apple had released a Rapid Security Response (RSR) update for the three operating systems, i.e. iOS 16.5.1 (c), iPadOS 16.5.1 (c), and macOS 13.4.1 (c), a couple of weeks ago.  The zero-day threat, which was tracked under CVE-2023-37450, could have allowed arbitrary code execution in web pages. Apple addressed the bug by improving some checks. The Cupertino company had initially pulled the updates after many users had reported that the new firmware prevented Safari from working on some websites including Facebook, Instagram, Zoom to name a few. However, Apple resumed the updates after fixing the problem.  If you had not installed the RSR update, don’t worry, the same security fix is included in iOS 16.6, macOS 13.5 and iPadOS 16.6.

Another critical zero-click exploit fixed in iOS 16.6, macOS 13.5 and iPadOS 16.6

A total of 16 security issues in iOS and iPadOS, and 29 bugs in macOS, were discovered to affect various parts of the operating systems. One of the two critical vulnerabilities that iOS 16.6, macOS 13.5 and iPadOS 16.6 ship with is the same that I described above. The other zero-day vulnerability was tracked as CVE-2023-38606. According to the release notes that the company has published on its support portal, the exploit could allow apps to modify sensitive kernel state.  Apple says it affected versions of iOS that were released before iOS 15.7.1. It has resolved the issue by improving the state management in the operating systems. Apple has credited Valentin Pashkov, Mikhail Vinogradov, Georgy Kucherin, Leonid Bezvershenko, and Boris Larin of Kaspersky Labs for discovering and reporting the issue. The security researchers had published a paper about the exploit which affected iMessage, they had termed the zero-click threat as Operation Triangulation.

The iOS 16.6 update is available for the iPhone 8 and later, while the iPadOS 16.6 update is available for the iPad Pro (3rd generation) and later, iPad Air (3rd generation) and later, and iPad mini (5th generation).

Please refer to the change log for macOS 13.5 Ventura, iOS 16.6 and iPadOS 16.6 to learn more about the other bugs that were patched in the operating systems.
