What is Microsoft Office Word Viewer? How does MS relate to this bulletin MS? The Office component discussed in this article is part of the Office Suite that I have installed on my system; however, I did not choose to install this specific component. Will I be offered this update? Yes, if the version of the Office Suite installed on your system shipped with the component discussed in this bulletin, the system will be offered updates for it whether the component is installed or not.
The detection logic used to scan for affected systems is designed to check for updates for all components that shipped with the particular Office Suite and offer the updates to a system. Users who choose not to apply an update for a component that is not installed, but is included in their version of the Office Suite, will not increase the security risk of that system. On the other hand, users who do choose to install the update will not have a negative impact on the security or performance of a system.
Does the offer to update a non-vulnerable version of Microsoft Office constitute an issue in the Microsoft update mechanism? No, the update mechanism is functioning correctly in that it detects a lower version of the files on the system than in the update package and thus, offers the update. Why is this update only Important for all affected versions of Word? Microsoft Office Word and later versions have a built-in feature that prompts a user to Open, Save, or Cancel before opening a document.
This mitigating factor reduces the vulnerability from Critical to Important because the vulnerability requires more than a single user action to complete the exploit.
