high Nessus Plugin ID 135482

Synopsis

The Microsoft Word Products are affected by multiple vulnerabilities.

Description

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

- A remote code execution vulnerability exists when Microsoft Office improperly loads arbitrary type libraries. 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-2020-0760)

- A remote code execution vulnerability exists in Microsoft Word software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user. (CVE-2020-0980)

Solution

Microsoft has released the following security updates to address this issue:
-KB4484300
-KB4484319
-KB4484295

For Office 365, Office 2016 C2R, or Office 2019, ensure automatic updates are enabled or open any office app and manually perform an update.
