Apple announced that it will be bringing the iOS 12.5.4 version to older iPhones and iPads. The main objective of this update is not an upgrade on features, instead it is important security updates. Even though the devices to which this update is being launched for are old, this move from Apple proves that it still cares about their customers, and their main goal through this update is to protect its consumers.
Most of the below mentioned devices did not get iOS 13, but the company has provided them with important security updates regularly. These devices for which the 12.5.4 is rolling out include: iPad Air, iPad Mini 2, iPad Mini 3, 6th Gen iPod touch, iPhone 5s, iPhone 6 and iPhone 6 Plus.
The iOS 12.5.4 update includes Security fix and two WebKit issue fixes. One of the WebKit issues was related to a memory corruption issue and the other one is used after a free issue with improved memory management reported by an anonymous researcher. In terms of the security issue that this new update addresses: a memory corruption issue with the ASN.1 decoder. This issue later led to arbitrary code execution.
On the iOS version update for the earlier phones and devices, Apple says, “This update provides important security fixes and is recommended for all users.” The company has also suggested to the users to visit their securities updates webpage to understand the update and learn more about it.
The company is currently focusing on its latest iOS 15 launch which provides important new features including the new Focus mode and the all new FaceTime features.
