TITLE

plural Apple Product CoreGraphics Vulnerability in arbitrary code execution in components

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 10.1 is affected. macOS before 10.12.1 is affected. tvOS before 10.0.1 is affected. watchOS before 3.1 is affected. The issue involves the "CoreGraphics" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted JPEG file. Apple macOS, watchOS, iOS and tvOS are prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code with elevated privileges, obtain sensitive information and overwrite arbitrary files. Failed exploit attempts may result in a denial-of-service condition. Versions prior to iOS 10.1, watchOS 3.1, macOS 10.12.1 and tvOS 10.0.1 are vulnerable. Apple iOS is an operating system developed for mobile devices; tvOS is a smart TV operating system; watchOS is a smart watch operating system. CoreGraphics is an iOS built-in drawing framework component.
