TITLE

plural Apple Used in products Webkit Vulnerability in arbitrary code execution in components

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 11.4 is affected. iOS before 11.3.1 is affected. Safari before 11.1 is affected. iCloud before 7.5 on Windows is affected. iTunes before 12.7.5 on Windows is affected. tvOS before 11.4 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. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within of the Array.splice method. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. WebKit is prone to multiple memory corruption vulnerabilities. Failed exploit attempts may result in a denial-of-service condition. Both Apple iOS and Safari are products of Apple (Apple). Apple iOS is an operating system developed for mobile devices; Safari is a web browser that is the default browser included with Mac OS X and iOS operating systems. WebKit is a set of open source web browser engines jointly developed by companies such as KDE, Apple (Apple), and Google (Google), and is currently used by browsers such as Apple Safari and Google Chrome. A memory corruption vulnerability exists in the WebKit component of Apple iOS versions prior to 11.3.1 and Safari versions prior to 11.1. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2018-04-24-3 Safari 11.1 (v. 11605.1.33.1.4, 12605.1.33.1.4, and 13605.1.33.1.4) may be obtained from the Mac App Store. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2018-7-23-4 Additional information for APPLE-SA-2018-06-01-6 tvOS 11.4 tvOS 11.4 addresses the following: Bluetooth Available for: Apple TV 4K Impact: An attacker in a privileged network position may be able to intercept Bluetooth traffic Description: An input validation issue existed in Bluetooth.
