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. Safari before 11.1.1 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 (buffer overflow 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 SVG elements. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. 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. The following products and versions are affected: Apple iOS prior to 11.4; Safari prior to 11.1.1; Windows-based iCloud prior to 7.5; Windows-based iTunes prior to 12.7.5; tvOS prior to 11.4. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 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.
