Security Update for Microsoft Office (January 2018) (macOS)

High Nessus Plugin ID 106189

Synopsis

An application installed on the remote macOS or Mac OS X host is affected by multiple remote code execution vulnerabilities.

Description

The Microsoft Office 2016 application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by the following vulnerabilities:

- 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-2018-0792)

- A remote code execution vulnerability exists in the way that Microsoft Outlook parses specially crafted email messages. An attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-0793)

- 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-2018-0794)

- A spoofing vulnerability exists when Microsoft Outlook for MAC does not properly handle the encoding and display of email addresses. This improper handling and display may cause antivirus or antispam scanning to not work as intended. (CVE-2018-0819)

Solution

Microsoft has released a set of patches for Microsoft Office 2016 for Mac.
