Security Updates for Microsoft Excel Products (July 2019)

High Nessus Plugin ID 126580

Synopsis

The Microsoft Excel Products are affected by multiple vulnerabilities.

Description

The Microsoft Excel Products are missing security updates. They are, 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. 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-2019-1110, CVE-2019-1111)

Solution

Microsoft has released the following security updates to address this issue:
-KB4464565
-KB4464572
-KB4475513

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