Apple accidentally reopens security flaw in latest iOS version

Vulnerability could be exploited to gain control of iPhone, users are warned

Apple users are being warned to exercise particular caution over their cybersecurity for the next few days, after the company mistakenly reopened a security flaw in the latest version of iOS.

In iOS 12.4, released last month, Apple fixed a number of security bugs, as well as enabling support for the Apple Card in the US. But in doing so, the company accidentally reversed a security fix it had previously patched in iOS 12.3 at the end of April.
