CVE-2016-7612

TITLE

plural Apple Vulnerability in the kernel component of a product that allows arbitrary code execution in privileged contexts

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 10.2 is affected. macOS before 10.12.2 is affected. watchOS before 3.1.3 is affected. The issue involves the "Kernel" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. Apple macOS, watchOS, iOS, and tvOS are prone to multiple security vulnerabilities. Failed exploit attempts may result in a denial-of-service condition. Versions prior to iOS 10.2, watchOS 3.1.1, macOS 10.12.2, and tvOS 10.1 are vulnerable. Apple iOS is an operating system developed for mobile devices; watchOS is an operating system for smart watches.
