TITLE

plural Apple Memory corruption vulnerability in products

DESCRIPTION

Multiple memory corruption issues were addressed with improved memory handling. This issue affected versions prior to iOS 11.4.1, tvOS 11.4.1, Safari 11.1.2, iTunes 12.8 for Windows, iCloud for Windows 7.6. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari. 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 WebGLRenderingContext's drawElements method. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access outside of an allocated buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. Apple iOS, etc. are all products of Apple (Apple). Apple iOS is an operating system developed for mobile devices. tvOS is a smart TV operating system. Safari is a web browser developed as the default browser included with MacOSX 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. Currently there is no information about this vulnerability, please keep an eye on CNNVD or vendor announcements. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201808-04 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: WebkitGTK+: Multiple vulnerabilities Date: August 22, 2018 Bugs: #652820, #658168, #662974 ID: 201808-04 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in WebKitGTK+, the worst of which may lead to arbitrary code execution.
