  - A remote code execution vulnerability exists in Microsoft Excel     software when the software fails to properly handle objects in     memory. An attacker who successfully exploited the vulnerability     could run arbitrary code in the context of the current user. If     the current user is logged on with administrative user rights, an     attacker could take control of the affected system. An attacker     could then install programs; view, change, or delete data; or     create new accounts with full user rights. Users whose accounts     are configured to have fewer user rights on the system could be     less impacted than users who operate with administrative user     rights. (CVE-2018-8331)
