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 conduct cross-site scripting attacks.

A remote user can create specially crafted content that, when loaded by the target user, will trigger a memory corruption error in Chakra and execute arbitrary code on the target user's system [CVE-2018-8541, CVE-2018-8542, CVE-2018-8543, CVE-2018-8551, CVE-2018-8555, CVE-2018-8556, CVE-2018-8557, CVE-2018-8588].

A remote user can host content from one domain and then inject it into another domain [CVE-2018-8567].

Qixun Zhao of Qihoo 360 Vulcan Team, Jonathan Jacobi (@j0nathanj) of MSRC-IL, Microsoft Chakra Core Team, Anonymous (via iDefense Labs), and dannywei of Tencent Security Xuanwu 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 access the target user's cookies (including authentication cookies), if any, associated with the site running the Microsoft Edge software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   The vendor has issued a fix.
