high Nessus Plugin ID 108296

Synopsis

The Microsoft Office Products are missing a security update.

Description

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

- An information disclosure vulnerability exists when Microsoft Office software reads out of bound memory due to an uninitialized variable, which could disclose the contents of memory. An attacker who successfully exploited the vulnerability could view out of bound memory. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. The security update addresses the vulnerability by properly initializing the affected variable. (CVE-2018-0919)

- A remote code execution vulnerability exists in Microsoft Office software when the Office 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-2018-0922)

Solution

Microsoft has released KB4011673 to address this issue.
