CVE-2016-7621

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 local users to execute arbitrary code in a privileged context or cause a denial of service (use-after-free) via unspecified vectors. Apple macOS, watchOS, iOS, and tvOS are prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, obtain sensitive information and bypass security restrictions. 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. CVE-2017-2363: lokihardt of Google Project Zero Installation note: Instructions on how to update your Apple Watch software are available at https://support.apple.com/kb/HT204641 To check the version on your Apple Watch, open the Apple Watch app on your iPhone and select "My Watch > General > About". Alternatively, on your watch, select "My Watch > General > About". -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2016-12-13-6 Additional information for APPLE-SA-2016-12-12-3 tvOS 10.1 tvOS 10.1 addresses the following: Audio Available for: Apple TV (4th generation) Impact: Processing a maliciously crafted file may lead to arbitrary code execution Description: A memory corruption issue was addressed through improved input validation.
