Today Apple has released a small update to iOS for iPhone and iPad devices. The update is iOS 11.3.1 and addresses a handful of security flaws found in the mobile platform. The update is a relatively small at 105MB that should take less than 10 minutes to download and install based on your connectivity.
As for fixes, there are four outlined in the release notes having to do with elevated privileges or malicious code. First, the Crash Reporter was patched against a memory corruption issue that could allow for elevated privileges to happen. This error was found by Google Project Zero.
The next issue addressed was with LinkPresentation. This bug could potentially allow for the processing of maliciously crafted text messages on how URLs were handled.
Finally two WebKit issues were addressed in this update. In both cases, a memory corruption issue was addressed that could allow for arbitrary code execution to happen. One of these bugs was found by Google Project Zero while the other was found by Trend Micro.
The update to iOS 11.3.1 is rolling out now and likely is already available for you to download to your devices. Just go to Settings>General>Software Update to check for it.
