It is, therefore, affected by multiple vulnerabilities :
- 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. (CVE-2018-0920, CVE-2018-1011,
