TITLE

Apple Safari BoundFunction Out-Of-Bounds Access Remote Code Execution Vulnerability

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 BoundFunction objects. By performing actions in JavaScript, an attacker can trigger a memory access past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of the current process. WebKit is prone to multiple memory-corruption vulnerabilities. These issues affect the following technologies and versions: iCloud for Windows 7 Safari prior to 11 tvOS prior to 11 iTunes for Windows prior to 12.7. 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 one of the web browser engine components. A security vulnerability exists in the WebKit component of several Apple products. Installation note: Safari 11 may be obtained from the Mac App Store. ------------------------------------------------------------------------ WebKitGTK+ Security Advisory WSA-2017-0008 ------------------------------------------------------------------------ Date reported : October 18, 2017 Advisory ID : WSA-2017-0008 Advisory URL : https://webkitgtk.org/security/WSA-2017-0008.html CVE identifiers : CVE-2017-7081, CVE-2017-7087, CVE-2017-7089, CVE-2017-7090, CVE-2017-7091, CVE-2017-7092, CVE-2017-7093, CVE-2017-7094, CVE-2017-7095, CVE-2017-7096, CVE-2017-7098, CVE-2017-7099, CVE-2017-7100, CVE-2017-7102, CVE-2017-7104, CVE-2017-7107, CVE-2017-7109, CVE-2017-7111, CVE-2017-7117, CVE-2017-7120, CVE-2017-7142.
