Apple has released the latest version of its mobile OS on Wednesday, and in it has fixed over 50 vulnerabilities, many of which are very serious:Two vulnerabilities allowed a local attacker to escalate privileges and install unverified (likely malicious) applicationsA validation issue in the handling of update check responses allowed an attacker with a privileged network position to cause an iOS device to think that it is up to date even when it is notTwo vulnerabilities in CoreGraphics made it possible for a maliciously crafted PDF file to terminate apps or execute arbitrary codeSeveral vulnerabilities in the IOHIDFamily kernel extension made it posible for a malicious app to read kernel pointers, which can be used to bypass kernel address space layout randomization, or to execute arbitrary code with system privileges (the latter was also made possible by the existence of several IOKit bugs)A Libnotify bug allowed a malicious application may be able to execute arbitrary code with root privilegesTwo Safari vulnerabilities made it possible for attackers and websites to intercept or harvest user credentials12 WebKit bugs could have been misused by attackers to execute arbitrary code on the device by simply creating a malicious website and tricking users into visiting it.With iOS 8, Apple has also updated its certificate trust policy and has randomised the MAC address to prevent potential device tracking attacks via passive WiFi scans.
Apple has announced that the two-step verification option for iCloud accounts now also extends to iCloud backups, preventing attackers who know the target's password from installing the target's backup on a new device and, thusly, from accessing the information contained in it.
Apple announced Apple Pay, a new category of service that works with iPhone 6 and iPhone 6 Plus through a NFC antenna design, a dedicated chip called the Secure Element, and the security and convenience of Touch ID.
Apple has built a payment system by first rolling out the “second factor”—the biometric Touch ID—and then by rolling out the first factor: the payment application and API.
Apple has released a statement denying that iCloud was hacked to steal nude photos of celebrities.
