TITLE

Apple iOS and Safari Used in etc. WebKit Vulnerable to arbitrary code execution

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. Safari before 10.1.1 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. Apple iOS and Safari Used in etc. 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 cached stylesheets. The issue results from the lack of validating the existence of an object prior to performing operations on the object. 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 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 in Apple iOS versions prior to 10.3.2 and Safari versions prior to 10.1.1. =========================================================================== Ubuntu Security Notice USN-3376-1 August 02, 2017 webkit2gtk vulnerabilities =========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.04 LTS Summary: Several security issues were fixed in WebKitGTK+.
