Apple recently released iOS 17.1.2, a minor update focusing on security fixes for iPhones and iPads. If you are wondering what new iOS 17.1.2 Features are, we have covered everything you need to know about the latest iOS update for your iPhone, along with iOS 17.2 release date.
What’s New in iOS 17.1.2?
On December 1st, 2023, Apple released iOS 17.1.2 for compatible iPhones and the corresponding iPadOS 17.1.2 for iPads. This is considered a minor “point update” since it comes between the more significant iOS 17.1 and upcoming iOS 17.2 releases.
The main purpose of iOS 17.1.2 is to patch two actively exploited WebKit vulnerabilities that could allow hackers to access sensitive information or even take control of a device. The update does not contain any major new features or design changes.
iOS 17.1.2: Technical Details
Here are some key technical details about the iOS 17.1.2 update:
- Size: Around 526MB, varying by device
- Build Number: 21B101
- Modem Firmware: 1.12.02
The update is available for all devices capable of running iOS 17.
Security Fixes in iOS 17.1.2
As mentioned above, the main focus of this update is security. Specifically, it patches two actively exploited WebKit vulnerabilities:
- A bug allowing sensitive information disclosure
- A memory corruption bug allowing arbitrary code execution
Both issues impact WebKit, the browser engine powering Safari and other apps using web views. Apple indicates these bugs were exploited in iOS versions prior to 16.7.1. By installing the latest update, users can protect themselves from these vulnerabilities being used to attack their devices.
Any Other Changes or Improvements?
Beyond the security fixes, iOS 17.1.2 does not contain any major new features or changes that typical users would notice. There are no fixes mentioned for recent Wi-Fi or wireless charging bugs some users have experienced.
However, some benchmark tests show minor performance improvements over iOS 17.1.1, especially for multicore scores. So, users may see slightly better system performance after updating.
Battery life is unlikely to change significantly coming from the previous iOS 17.1.1 version. But users updating from much older iOS builds could still benefit from cumulative battery life optimizations.
Corresponding Updates: macOS and More
Alongside iOS 17.1.2, Apple also released macOS Ventura 14.1.2, which contains the same WebKit security patches. So, Mac users should update as well to protect from potential attacks leveraging those bugs.
Apple also updated many of its pro creative apps for Mac and iPad, including major new versions of Final Cut Pro, iMovie, Compressor, and Logic Pro. These updates bring a variety of new features and performance enhancements.
Should You Install iOS 17.1.2?
For most iPhone and iPad users, installing iOS 17.1.2 and iPadOS 17.1.2 is recommended. The security fixes alone make it worthwhile, protecting your device from two actively exploited vulnerabilities.
Upgrading is even more important if you browse the web frequently and rely on your device’s security. With the fixes applied, you’ll have peace of mind knowing your iPhone or iPad is protected from these recently used attack vectors.
Users not yet seeing iOS 17.2 betas can feel comfortable updating to 17.1.2 in the meantime. And going forward, be sure to stay current with any future iOS updates to get the latest security patches from Apple.
What’s Next: iOS 17.2 Release Date
While iOS 17.1.2 was a relatively minor update, iOS 17.2 promises to bring more substantial changes. iOS 17.2 is currently in beta testing and is expected to see its official public release around the second week of December 2023.
iOS 17.2 will deliver new features, design tweaks, and performance improvements. Some areas getting upgrades include iCloud sharing, Apple Pay Later, Apple Home architecture, and much more.
The update will also likely fix lingering issues like Wi-Fi and wireless charging problems introduced in earlier iOS 17 versions.
Overall, iOS 17.2 represents a more significant update for iPhones than the security-minded iOS 17.1.2 release. Users can look forward to an improved experience across many apps and services after upgrading.
Final Words
iOS 17.1.2 is a small but important update for iPhones, iPads, and Macs. By patching two actively exploited security bugs, it prevents attackers from gaining access to user devices and data. All Apple device owners should install the latest updates as soon as possible.
While light on new features, iOS 17.1.2 paves the way for the more action-packed iOS 17.2 release expected within the next couple of weeks. So, stay tuned for additional enhancements and fixes coming very soon straight from Apple.
