TITLE

plural Apple Used in products WebKit Vulnerable to arbitrary code execution

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 10.2.1 is affected. Safari before 10.0.3 is affected. iCloud before 6.1.1 is affected. iTunes before 12.5.5 is affected. tvOS before 10.1.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site. WebKit is prone to multiple memory-corruption vulnerabilities. Attackers can exploit this issue to execute arbitrary code on the affected system. Failed exploit attempts may result in a denial-of-service condition. Apple iOS, iCloud for Windows, iTunes for Windows, Safari, and tvOS are all products of the American company Apple (Apple). Apple iOS is an operating system developed for mobile devices; Safari is a web browser that comes with the Mac OS X and iOS operating systems by default. WebKit is an open source web browser engine developed by the KDE community and is currently used by browsers such as Apple Safari and Google Chrome. A memory corruption vulnerability exists in the WebKit component of several Apple products. The following products and versions are affected: Apple iOS prior to 10.2.1, iCloud on Windows prior to 6.1.1, iTunes prior to 12.5.5 on Windows, Safari prior to 10.0.3, tvOS 10.1 Versions prior to .1. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2017-01-23-4 tvOS 10.1.1 tvOS 10.1.1 is now available and addresses the following: Kernel Available for: Apple TV (4th generation) Impact: An application may be able to execute arbitrary code with kernel privileges Description: A buffer overflow issue was addressed through improved memory handling.
