Apple releases an emergency update for older iPhones

Apple: Normally, when Apple announces an emergency update for iPhone, it refers to the models that support the latest version of its iOS system. But from time to time it is the other Apple phones that need to be patched. And in this case, the security alert goes to those who still use iOS 12, not iOS 14 – or the future iOS 15.

Apple’s emergency update came out yesterday Monday, and it fixes up to three vulnerabilities that allowed the potential execution of arbitrary code, two of which, according to Apple, “may have been actively exploited.” To do so, simply go to Settings> General> Update. software, and Download and Install the update.
