Apple recently released iOS 17.4.1 and macOS Sonoma 14.4.1, both with two security patches. For users of older versions of macOS, the company has released a separate update for Safari, its own web browser, with the same fixes as in macOS 14.4.1.
Safari update available for older versions of macOS
As detailed on Apple's website, Safari 17.4.1 fixes an exploit in WebRTC that allowed arbitrary code execution when processing images. Apple says that “an out-of-bounds write issue has been resolved with improved input validation.” and thanks Nick Galloway of Google Project Zero for discovering and reporting the exploit.
A separate Safari update is available for Macs running macOS Monterey (version 12) and macOS Ventura (version 13), as there are Macs running which cannot be updated to macOS Sonoma, the latest version of macOS available.
Apple also released iOS 16.7.7 to fix the WebRTC exploit on some iPhone and iPad models not supported by iOS 17, such as the iPhone 8 and iPhone X. It's always important to update your devices to protect them from such exploits.
To update Safari on your Mac, open System Preferences. application, click the General menu and select Software Update. Wait for your Mac to find an available update, then click Update Now. To update your iOS device, go to Settings > General > Software Update. It's worth noting that not every older device receives security patches.
