Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 10, 11
Description:   Multiple vulnerabilities were reported in Microsoft Edge. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can obtain potentially sensitive information on the target system. A remote user can spoof servers. Microsoft Internet Explorer is affected.

A remote user can create specially crafted content that, when loaded by the target user, will trigger an object memory handling error in the Chakra scripting engine and execute arbitrary code on the target user's system [CVE-2018-8367, CVE-2018-8456, CVE-2018-8459, CVE-2018-8465, CVE-2018-8466, CVE-2018-8467].

A remote user can create specially crafted content that, when loaded by the target user, will trigger an object memory handling error and execute arbitrary code on the target user's system [CVE-2018-8354].

A remote user can create specially crafted content that, when loaded by the target user, will read privileged data across trust boundaries [CVE-2018-8315].

A remote user can create specially crafted HTML content that, when loaded by the target user, will spoof a target web site [CVE-2018-8425].

The Microsoft Edge Fetch API does not properly handle a filtered response type. A remote user can access potentially sensitive information from a different origin as URL parameters [CVE-2018-8366].

A remote user can exploit a separate vulnerability and then escape from the AppContainer sandbox in the browser [CVE-2018-8469, CVE-2018-8463].

A remote user can create specially crafted content that, when loaded by the target user, will trigger an object memory handling error and access potentially sensitive information on the target user's system [CVE-2018-8452].

A remote user can create specially crafted content that, when loaded by the target user, will trigger an object memory handling error and execute arbitrary code on the target user's system [CVE-2018-8457]. This can also be exploited via an embedded ActiveX control marked "safe for initialization" in an application or via a Microsoft Office document that hosts the scripting rendering engine.

A remote user can create specially crafted content that, when loaded by the target user, will trigger an object memory handling error in the Microsoft Edge PDF Reader and execute arbitrary code on the target user's system [CVE-2018-8464].

Yuki Chen of Qihoo 360 Vulcan Team, Qixun Zhao of Qihoo 360 Vulcan Team, Anonymous (via Trend Micro's Zero Day Initiative), Jonathan Birch of Microsoft Corporation, Michael Holman, Microsoft Chakra Core Team, Jun Kokatsu, Windows & Devices Group - Operating System Security Team, James Lee @Windowsrcer of Kryptos Logic, Yu Zhou of Ant-financial Light-Year Security Lab, Lokihardt of Google Project Zero, and Omri Herscovici of Check Point reported these vulnerabilities.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can obtain potentially sensitive information on the target system.

A remote user can spoof content.

Solution:   Microsoft has issued a fix for CVE-2018-8315, CVE-2018-8452, and CVE-2018-8457 for Microsoft Internet Explorer.
