Synopsis

The Microsoft Office Products are affected by multiple vulnerabilities.

Description

The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :

- Microsoft has released an update for Microsoft Office that provides enhanced security as a defense-in-depth measure.

- A remote code execution vulnerability exists in Microsoft Office 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-2017-11854)
