Anyone with an iPhone, iPad, or iMac running the latest operating systems is strongly advised by Apple to download security updates for those devices as soon as possible.
A senior technology expert said the vulnerability meant “editing online content could lead to malicious behavior.” Alternatively, a hacker can, for example, plant malware on devices via an infected website. More importantly, Apple said that the bug, which was reported by an anonymous security researcher, may have already been exploited, so it is better to get the update now.
To update manually on iPhone and iPad, go to Settings, then General, select Software Update near the top of the display and then follow the instructions.
To update macOS, select the Apple icon in the lower left corner of the display, then select System Settings, then General, and then Software Update. Then you will be guided along the way.
If automatic updates are enabled on your device, you don’t need to do anything, although it only takes a second to check if you’re ready.
Monday’s security update is part of Apple’s Rapid Security Response (RSR) system. It has been testing this system since last year, and in May it released its first RSR update.
RSR updates bring important security improvements, are highly monitored, and do not require major software updates. In this way, the outputs can be released more efficiently and are often faster to install. Apple says that when RSR is installed, a letter appears in the code after the software version number, for example, iOS 16.5.1 (a).
Apple also says that RSR updates are only available for the latest versions of iOS, iPadOS, and macOS, starting with iOS 16.4.1, iPadOS 16.4.1, and macOS 13.3.1.
