Multiple Vulnerabilities in Apple Products Could Allow for Arbitrary Code Execution

Read Time:56 Second

Multiple vulnerabilities have been discovered in Apple Products, the most severe of which could allow for arbitrary code execution.

Safari is a graphical web browser developed by Apple.
iOS is a mobile operating system for mobile devices, including the iPhone, iPad, and iPod touch.
iPadOS is the successor to iOS 12 and is a mobile operating system for iPads.
macOS Monterey is the 18th and current major release of macOS.
macOS Big Sur is the 17th release of macOS.
macOS Catalina is the 16th major release of macOS
watchOS is the mobile operating system for Apple Watch and is based on the iOS operating system.
tvOS is an operating system for fourth-generation Apple TV digital media player.
Xcode is Apple’s integrated development environment for macOS
Successful exploitation of the most severe of these vulnerabilities could result in arbitrary code execution within the context of the application, an attacker gaining the same privileges as the logged-on user, or the bypassing of security restrictions. Depending on the permission associated with the application running the exploit, an attacker could then install programs; view, change, or delete data.
