MS15-110: Security Updates for Microsoft Office to Address Remote Code Execution (3089440)

High Nessus Plugin ID 86374

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host has a version of Microsoft Office, Excel, Excel Viewer, SharePoint Server, Microsoft Office Compatibility Pack, or Microsoft Office Web Apps installed that is affected by multiple vulnerabilities :

- Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. A remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted file, resulting in execution of arbitrary code in the context of the current user. (CVE-2015-2555, CVE-2015-2557, CVE-2015-2558)

- An information disclosure vulnerability exists in the SharePoint InfoPath Forms Services due to improper parsing of document type definitions (DTD) in XML files.
A remote attacker can exploit this, via a crafted XML file, to browse the contents of arbitrary files on a SharePoint server. (CVE-2015-2556)

- A cross-site scripting vulnerability exists in Office Web Apps Server due to improper sanitization of crafted requests before returning it to the user. A remote attacker can exploit this to run arbitrary script code in the user's browser session. (CVE-2015-6037)

- A security feature bypass vulnerability exists in SharePoint due to improper enforcement of permission levels for applications or users. This allows Office Marketplace to inject JavaScript code that will persist in a SharePoint page. A remote attacker can exploit this to conduct a cross-site scripting attack, resulting in execution of arbitrary code in the user's browser session. (CVE-2015-6039)

Solution

Microsoft has released a set of patches for Office 2007, 2010, 2013, 2013 RT, 2016; SharePoint Server 2007, 2010, 2013; Microsoft Office Compatibility Pack SP3; Microsoft Excel Viewer; and Microsoft Office Web Apps 2010, 2013.
