iOS and macOS security update
Although Apple provided little information in the release notes, which simply state that the new versions “provide important security updates and are recommended for all users”, the company’s website sheds a little more light.
The bug is described as a “memory corruption issue” that has been “addressed with improved validation”. If the problem is not addressed, says Apple, cybercriminals could use “maliciously crafted web content” to perform remote code execution on affected devices.
The vulnerability (CVE-2021-1844) has been handed a high severity rating of 7.7/10, by the Common Vulnerability Scoring System (CVSS).
The iOS update is available for iPhone 6 models and newer, iPad Air 2 and newer, iPad mini 4 and newer, and iPod touch (7th generation). And the Mac update is available for macOS Big Sur.
If the update has not been deployed automatically, iOS users can perform a manual install by navigating to Settings > General and then selecting Software Update.
Mac owners, meanwhile, will need to find their way to the System Preferences panel via the Apple menu, and then click Software Update.
