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 is affected. Safari before 10.0.2 is affected. iCloud before 6.1 is affected. iTunes before 12.5.4 is affected. watchOS before 3.1.3 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. Apple Safari,iCloud, iTunes,iOS, WatchOS and tvOS are prone to a memory corruption vulnerability. An attacker can exploit this issue using a specifically crafted web content. Failed exploit attempts may result in a denial-of-service condition. The following versions are affected: Versions prior to Safari 10.0.2 Versions prior to iCloud for Windows v6.1 Versions prior to iTunes 12.5.4 Versions prior to iOS 10.2 Versions prior to tvOS 10.1 Versions prior to watchOS 3.1.1. Apple Safari, iCloud for Windows, iTunes, iOS, and tvOS are all products of the US company Apple. Apple Safari is a web browser that comes with the default browser on the Mac OS X and iOS operating systems; iTunes is a suite of media player applications. 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 security vulnerability exists in the WebKit component of several Apple products. ========================================================================== Ubuntu Security Notice USN-3191-1 February 06, 2017 webkit2gtk vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.10 - Ubuntu 16.04 LTS Summary: Several security issues were fixed in WebKitGTK+.
