Apple has released iOS 11.3.1 to iPhone, iPad, and iPod touch, the thirteenth official update to the iOS 11 operating system. The update comes a month after the company released the thrid major iOS 11 update - iOS 11.3. It can be downloaded for free on all eligible devices by going to Settings -> General -> Software Update.

According to Apple's release notes, iOS 11.3.1 includes a fix for display issues experienced on iPhone 8 with third-party repairs, which can disable the touch functionality of the screen. Asides from that, it also bring security and speed improvements for all iDevices.

iOS 11.3.1 improves the security of your iPhone or iPad and addresses an issue where touch input was unresponsive on some iPhone 8 devices because they were serviced with non-genuine replacement displays.

Note: Non-genuine replacement displays may have compromised visual quality and may fail to work correctly. Apple-certified screen repairs are performed by trusted experts who use genuine Apple parts. See for more information.
Apple has released a security update to the recent macOS 10.13.4 update called Security Update 2018-001 as well. The update addresses a memory corruption issue by improving error handling that allow an application to "gain elevated privileges, which leds to attackers to control your Mac. It patched the so-called maliciously crafted text message" vulnerability that could be used to spoof the user interface. (via AppleInsider).

Apple has just stopped signing iOS 11.2.6, meaning it is no longer possible to downgrade an iPhone, iPad, or iPod touch to software versions older than latest iOS 11.3 update. However, A zero day exploit has been discovered in iOS 11.3 that could helpful in developing a jailbreak for it.

When Apple stops signing a particular firmware, it essentially means that iTunes won’t allow you to restore it anymore. Instead, you are then prompted to update to the latest available firmware. In this case, that's iOS 11.3, an update that introduces several new feature like Business Chat and "Battery Health".

On the other hand, as we stated earlier, a zero day exploit was found in iOS 11.3, revealed Alibaba's Zheng, who's the Senior Security Engineer for the company said on his Twitter. Current iOS 11.1.2 jailbreak is based on a zero day exploit that eventually made to the public by Google Project Zero’s Ian Beer.

We are not clear if Alibaba will release the expolit to the public, but it's unlikely because the Chinese company previously demoed an iOS 11.2.1 jailbreak without releasing it. Still, if Alibaba refused to give it to jailbreak developers, there is a big chance that the exploit will be found by others. We will keep eyes on it.
