Apple on Monday released security updates for iOS, macOS, and watchOS to address three zero-day flaws and expand patches for a fourth vulnerability that the company said might have been exploited in the wild. The vulnerabilities all concern WebKit, the browser engine which powers Safari and other third-party web browsers in iOS, allowing an adversary to execute arbitrary code on target devices. The company said it’s aware of reports that the issues “may have been actively exploited” but, as is typically, failed to elaborate about the nature of attacks.
