CVE-2018-4117

TITLE

plural Apple Used in products WebKit Component fetch API Vulnerabilities that bypass the same origin policy

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 11.3 is affected. Safari before 11.1 is affected. iCloud before 7.4 on Windows is affected. iTunes before 12.7.4 on Windows is affected. watchOS before 4.3 is affected. The issue involves the fetch API in the "WebKit" component. It allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted web site. Google Chrome is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code in the context of the browser, obtain sensitive information, bypass security restrictions and perform unauthorized actions, or cause denial-of-service conditions. Information obtained may aid in further attacks. Versions prior to Chrome 68.0.3440.75 are vulnerable. Apple iOS, iCloud for Windows, iTunes for Windows, Safari, and tvOS are all products of the American company Apple (Apple). Apple iOS is an operating system developed for mobile devices; Safari is a web browser that comes with the Mac OS X and iOS operating systems by default. 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. ------------------------------------------------------------------------ WebKitGTK+ Security Advisory WSA-2018-0003 ------------------------------------------------------------------------ Date reported : April 04, 2018 Advisory ID : WSA-2018-0003 Advisory URL : https://webkitgtk.org/security/WSA-2018-0003.html CVE identifiers : CVE-2018-4101, CVE-2018-4113, CVE-2018-4114, CVE-2018-4117, CVE-2018-4118, CVE-2018-4119, CVE-2018-4120, CVE-2018-4122, CVE-2018-4125, CVE-2018-4127, CVE-2018-4128, CVE-2018-4129, CVE-2018-4133, CVE-2018-4146, CVE-2018-4161, CVE-2018-4162, CVE-2018-4163, CVE-2018-4165.
