CVE-2017-2473

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 10.3 is affected. macOS before 10.12.4 is affected. tvOS before 10.2 is affected. watchOS before 3.2 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. iOS is a mobile operating system developed by Apple. Apple Corps first announced this system at the Macworld conference on January 9, 2007. It was originally designed for the iPhone and later applied to iPod touch, iPad, and Apple TV. tvOS is a system developed by Apple. Based on iOS, tvOS is an operating system designed for the fourth generation of Apple TV. MacOS is a set of operating systems running on Apple Macintosh computers. watchOS is a mobile operating system for the Apple Watch developed by Apple. It is based on the iOS operating system and has many similar features. The "Kernel" component of many Apple products has a denial of service vulnerability. Apple iOS, tvOS, macOS and watchOS are prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, obtain sensitive information, cause a denial-of-service condition, perform unauthorized actions and gain elevated privileges; this may aid in launching further attacks. Versions prior to iOS 10.3, watchOS 3.2, macOS 10.12.4, and tvOS 10.2 are vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2017-03-27-5 watchOS 3.2 watchOS 3.2 is now available and addresses the following: Audio Available for: All Apple Watch models Impact: Processing a maliciously crafted audio file may lead to arbitrary code execution Description: A memory corruption issue was addressed through improved input validation.
