Category: iOS 11.3

With the release of iOS 11.3.1 last week, Apple has stopped signing iOS 11.3 meaning that iPhone and iPad owners can no longer downgrade from the latest build.  Long time Apple followers will know that this is normal for the Cupertino company to do after a release of an update or major version of the platform.

For the majority of iOS users, the removal of 11.3 won’t be a big deal.  Most owners don’t downgrade after an update unless there are bugs or other use impacting issues.  With virtually none reported, it was just a matter of when Apple stopped signing it.

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.
