TITLE

plural Apple Product etc. WebKit Vulnerable to arbitrary code execution

DESCRIPTION

WebKit in Apple iOS before 9.3.3, Safari before 9.1.2, and tvOS before 9.2.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, a different vulnerability than CVE-2016-4589, CVE-2016-4623, and CVE-2016-4624. 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 Array.slice. The issue lies in the failure to ensure that an array's length has not changed during processing of user-supplied arguments. An attacker can leverage this vulnerability to execute code within the context of the current process. Attackers can exploit these issues to execute arbitrary code, gain sensitive information or steal cookie-based authentication credentials and launch other attacks. Versions prior to iOS 9.3.3, tvOS 9.2.2 and Safari 9.1.2 are vulnerable. in the United States. 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; tvOS is a smart TV operating system. WebKit is an open source web browser engine developed by the KDE community and is currently used by browsers such as Apple Safari and Google Chrome. =========================================================================== Ubuntu Security Notice USN-3079-1 September 14, 2016 webkit2gtk vulnerabilities =========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS Summary: Several security issues were fixed in WebKitGTK+.
