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

and iPod player.

Who updated

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.

What for?

Of course, no new firmware featuresIt doesn't, but it has an equally important function - it fixes vulnerabilities and security issues associated with XNU, WebKit and CoreGraphics. Thus, a vulnerability for XNU allowed code to be executed with kernel privilege. In WebKit, “maliciously crafted web content” was used to execute code. And the CoreGraphics vulnerability worked by processing a malicious PDF file.

Essentially, by using these paths,attackers could gain administrator rights on your device and take over personal data. How actively the vulnerabilities were exploited and how many devices were affected is unknown.
