Today Apple started rolling out iOS 14.4.2, iPadOS 14.4.2, and watchOS 7.3.3. The company recommended that users upgrade as soon as possible. As with iOS / iPadOS 14.4.1 before, this update fixes a security vulnerability.
In addition, Apple has released a similar security update (12.5.2) for older devices like the iPhone 5S or 6 that will not run iOS 14.
The release notes for iOS 14.4.2 and iPadOS 14.4.2 are minimal and contain only the following:

The same applies to the watchOS update. All four software updates (iOS 14.4.2, iPadOs 14.4.2, iOS 12.5.2 and watchOS 7.3.3) should now be available for all users of supported devices. This is the second update since the release of iOS / iPadOS 14.4 and watchOS 7.3 in late January.
The update immediately prior to this update was also an urgent solution to a security vulnerability.
iOS 14.4 was a feature update, not just a security update or a bug fix, but the added features were relatively modest. These included the ability for the camera to read smaller QR codes than before, an option to manually classify Bluetooth devices to ensure desired behavior, and notifications to let users know if the camera was “not considered new, real Apple camera can be verified “. “”
