About CVE-2018-8463
   An elevation of privilege vulnerability exists in Microsoft Edge that could allow an attacker to escape from the AppContainer sandbox in the browser, aka "Microsoft Edge Elevation of Privilege Vulnerability." This affects Microsoft Edge. This CVE ID is unique from CVE-2018-8469.
   An elevation of privilege vulnerability exists in Microsoft Edge that could allow an attacker to escape from the AppContainer sandbox in the browser. An attacker who successfully exploited this vulnerability could gain elevated privileges and break out of the Edge AppContainer sandbox.
   The vulnerability by itself does not allow arbitrary code to run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (for example a remote code execution vulnerability and another elevation of privilege vulnerability) to take advantage of the elevated privileges when running.
   The security update addresses the vulnerability by modifying how Microsoft Edge handles sandboxing.

About CVE-2018-8468
   An elevation of privilege vulnerability exists when Windows, allowing a sandbox escape, aka "Windows Elevation of Privilege Vulnerability." This affects Windows 7, Windows Server 2012 R2, Windows RT 8.1, Windows Server 2008, Windows Server 2012, Windows 8.1, Windows Server 2016, Windows Server 2008 R2, Windows 10, Windows 10 Servers.
   An elevation of privilege vulnerability exists in Windows that allows a sandbox escape. An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system.
   This vulnerability by itself does not allow arbitrary code execution. However, the vulnerability could allow arbitrary code to run if an attacker uses it in combination with another vulnerability, such as a remote code execution vulnerability or another elevation of privilege vulnerability, that can leverage the elevated privileges when code execution is attempted.
   The security update addresses the vulnerability by correcting how Windows parses files.
