SecurityTracker Alert ID:  1036993
SecurityTracker URL:  http://securitytracker.com/id/1036993
CVE Reference:   CVE-2016-3267, CVE-2016-3331, CVE-2016-3382, CVE-2016-3386, CVE-2016-3387, CVE-2016-3388, CVE-2016-3389, CVE-2016-3390, CVE-2016-3391, CVE-2016-3392, CVE-2016-7189, CVE-2016-7190, CVE-2016-7194   (Links to External Site)
Date:  Oct 11 2016
Impact:   Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

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 gain elevated privileges. A remote user can bypass security controls on the target system. A remote user can obtain potentially sensitive information on the target system.

A remote user can create specially crafted content that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target user's system [CVE-2016-3331].

A remote user can create specially crafted content that, when loaded by the target user, will trigger a object memory handling error in the Scripting Engine and execute arbitrary code on the target user's system [CVE-2016-3382, CVE-2016-3386, CVE-2016-3390, CVE-2016-7189, CVE-2016-7190, CVE-2016-7194].

The browser does not properly secure private namespace [CVE-2016-3387, CVE-2016-3388]. A remote user that can exploit an independent vulnerability can then gain elevated permissions on the target namespace directory and gain elevated privileges on the target system.

A remote user can create specially crafted content that, when loaded by the target user, will trigger a object memory handling error and view potentially sensitive information on the target system [CVE-2016-3267].

The browser leaves authentication credentials in memory [CVE-2016-3391]. A user that can obtain a memory dump of the browser process can obtain the credentials.

A remote user can create specially crafted content that, when loaded by the target user, will bypass Edge Content Security Policy on the target system [CVE-2016-3392].

0011 (via Trend Micro's Zero Day Initiative (ZDI)), Anonymous (via Trend Micro's Zero Day Initiative (ZDI)), James Forshaw of Google Project Zero, Natalie Silvanovich of Google Project Zero, Richard Zhu (fluorescence) (via Trend Micro's Zero Day Initiative (ZDI)), Stefaan Truijen, working with NVISO, Adrian Toma, working with NVISO (internship), Daan Raman, working with NVISO, Wenxiang Qian of Tencent QQBrowser, Xiaoyin Liu with a hyperlink to Twitter page https://twitter.com/general_nfs, and Zheng Huang of the Baidu Security Lab 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 gain elevated privileges on the target system.

A remote user can bypass security controls on the target system.

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

Solution:   The vendor has issued a fix.

A patch matrix is available in the vendor advisory.
