The issue involves the \"Keychain\" component. It allows man-in-the-middle attackers to bypass an iCloud Keychain secret protection mechanism by leveraging lack of authentication for OTR packets. Apple macOS, iOS and tvOS are prone to a security bypass vulnerability. \nAttackers can exploit this issue to bypass security restrictions and perform unauthorized actions. \nThe following products are affected:\nVersions prior to Apple tvOS 10.2\nVersions prior to Apple iOS 10.3\nVersions prior to Apple macOS 10.12.4. in the United States. macOS Sierra is a dedicated operating system developed for Mac computers; iOS is a set of operating systems developed for mobile devices. Security is one of the information security and privacy protection components. An attacker could exploit this vulnerability to obtain or change session data protected by SSL/TLS",
