CVE-2017-7111

TITLE

plural Apple Used in products WebKit Vulnerable to arbitrary code execution

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 11 is affected. Safari before 11 is affected. iCloud before 7.0 on Windows is affected. iTunes before 12.7 on Windows is affected. tvOS before 11 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 the handling of regular expressions. 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 a memory-corruption vulnerability. Failed exploit attempts may result in a denial-of-service condition. 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 security vulnerability exists in the WebKit component of several Apple products. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2017-09-25-3 Additional information for APPLE-SA-2017-09-19-2 Safari 11 Safari 11 addresses the following: Safari Available for: OS X El Capitan 10.11.6, and macOS Sierra 10.12.6, macOS High Sierra 10.13 Impact: Visiting a malicious website may lead to address bar spoofing Description: An inconsistent user interface issue was addressed with improved state management.
