high Nessus Plugin ID 101371
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

An application installed on the remote Windows host is affected by multiple remote code execution vulnerabilities.

Description

The Microsoft Office application, Microsoft Office Compatibility Pack, or Microsoft Excel Viewer installed on the remote Windows host is missing a security update. It is, therefore, affected by multiple remote code execution vulnerabilities due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these vulnerabilities, by convincing a user to open a specially crafted document or to visit a specially crafted website, to execute arbitrary code in the context of the current user.

Note that KB2880514 for Office 2007 and KB3203468 for Office 2010 SP2 are only applicable to Office installations with the Galician language pack installed.

Solution

Microsoft has released a set of patches for Microsoft Office 2007, 2010, 2013, and 2016; Microsoft Excel 2007, 2010, 2013, and 2016;
Microsoft Excel Viewer 2007; and Microsoft Office Compatibility Pack.
