iOS 12.5.4 - Apple releases update for older iPhones and iPads

iPhone and iPad models that are not compatible with the current operating system versions can still be used. For example with iOS 12. Apple has published a security update for this purpose, which is intended to eliminate three vulnerabilities at once. The update is recommended for all users of iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3 and iPod touch (6th gen). The vulnerabilities that are being closed are according to Apple a faulty certificate check and two WebKit problems.

With iOS 12.5.4, Apple closes a certificate and two WebKit security holes on these iPhone and iPad models: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3 and iPod touch (6. Gene).

Update for older iPhone and iPad models to iOS 12.5.4

Apple rolled out the iOS 12.5.4 update yesterday. Its purpose is to prevent certificates or web content with malicious code from damaging the memory or the entire device. For both WebKit problems, the document linked above states "Apple is aware of a report that this issue may have been actively exploited", Which translates as"Apple is aware of a report that this issue may have been actively exploited". So if you use your iOS 12 device for web applications, surfing in Safari and other Internet matters, you should definitely install the update. And you are not doing anything wrong with it either.

How to get the update: Settings -> General -> software update

Overview of Apple security updates

Der laut official page about current security updates Apple's update to 12.5.4 is the first in June 2021. Before that, seven updates were listed for May 24, 2021 alone. These affect current Mac systems such as macOS Big Sur, macOS Catalina and macOS Mojave. There were also updates for iOS 14.6, iPadOS 14.6 and watchOS 7.5. Incidentally, I recommend the English version of the support document linked at the beginning of the paragraph. As with other Apple documents, the German translation back a bit. The update to iOS 12.5.4 is (currently) not even listed there.
