The iPhone 5s and iPhone 5c are expected to receive an update in the coming weeks that will improve their security features.
A new iOS security update for the devices is currently in the works and is expected to be released in a few days.
According to reports, the iOS update for both devices is expected with a security fix for the following vulnerabilities:CVE-2017-1288: The application might open arbitrary files with read permissions.CVE-2018-879: The app might cause a crash on launch.
This will be a minor security update and is likely to not affect your iPhone or iPad.
However, it is expected that the update will address some known issues for these devices.
As a precaution, Apple is asking users to update their devices to the latest version of iOS.
The update is expected in the next few days and is already available on the App Store.
