Apple releases iOS 12.5.5 update for older smartphones

Recently, Apple unexpectedly began distributing an update for older models of smartphones, tablets and iPod.

So, iOS 12.5.5 has become available for the following devices:

  • iPhone 5s
  • iPhone 6
  • iPhone 6 Plus
  • 1st generation iPad Air
  • iPad mini 2
  • iPad mini 3
  • iPod touch 6th generation

You can download the update in Settings – General – Software update.

Of course, the firmware does not bring any new functions, but it has an equally important function – it eliminates vulnerabilities and security problems associated with XNU, WebKit and CoreGraphics. For example, a vulnerability for XNU allowed code to be executed with kernel privileges. WebKit used “maliciously crafted web content” to execute code. And the CoreGraphics vulnerability worked by processing a malicious PDF file.

In fact, by using these paths, attackers could gain administrator rights on your device and take over your personal data. It is not known how the vulnerabilities were actively exploited and how many devices were damaged.
