An issue was discovered in certain Apple products. Safari before 11.1 is affected. The issue involves the "WebKit" component. A Safari cross-site scripting (XSS) vulnerability allows remote attackers to inject arbitrary web script or HTML via a crafted URL. contains a script injection vulnerability (CWE-81) in the processing of displaying an error page when it fails to verify server certificates. In an error page Safari displays when it fails to verify server certificates, a domain name of the website accessed is output straightly. Therefore by exploiting this vulnerability, an arbitrary script may be executed on the user's web browser via an error page that is displayed when a user is led to visit a website with a specially crafted domain name. Yuji Tonai of NTT Communications Corporation reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.If a user is led to visit a website with a specially crafted domain name, an arbitrary script may be executed on the user's web browser. Apple Safari is prone to is prone to multiple security vulnerabilities. An attacker may exploit these vulnerabilities to spoof the originating URL of a trusted web site. These issues may allow a remote attacker to carry out phishing-style attacks. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Apple Safari is a web browser of Apple (Apple), 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. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 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.
