Descriptions

Microsoft Internet Explorer 10 and 11 and Microsoft Edge do not properly restrict access to private namespaces, which allows remote attackers to gain privileges via unspecified vectors, aka "Microsoft Browser Elevation of Privilege Vulnerability," a different vulnerability than CVE-2016-3388.

Microsoft Internet Explorer 10 y 11 y Microsoft Edge no restringe adecuadamente el acceso a espacios de nombres privados, lo que permite a atacantes remotos obtener privilegios a través de vectores no especificados, vulnerabilidad también conocida como "Microsoft Browser Elevation of Privilege Vulnerability", una vulnerabilidad diferente a CVE-2016-3388.

The isolated private namespace created by ierutils has an insecure boundary descriptor which allows any non-appcontainer sandbox process (such as chrome) or other users on the same system to gain elevated permissions on the namespace directory which could lead to elevation of privilege.
