Synopsis

The remote Windows host is affected by multiple remote code execution vulnerabilities.

Description

The remote Windows host has a version of Microsoft Office, Excel, Excel Viewer, SharePoint Server, Microsoft Office Compatibility Pack, Microsoft Office Web Apps, and/or Microsoft SharePoint Foundation installed that is affected by one or more of the following 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 in Microsoft Office, resulting in execution of arbitrary code in the context of the current user. (CVE-2015-2520, CVE-2015-2521, CVE-2015-2523)

- A cross-site scripting vulnerability exists in SharePoint due to improper sanitization of user-supplied web requests. A remote attacker can exploit this vulnerability, via a specially crafted web request, to execute arbitrary script code in the context of the current user. (CVE-2015-2522)

- A remote code execution vulnerability exists in Microsoft Office due to improper handling of malformed graphics images. A remote attacker can exploit this vulnerability by convincing a user to open a file or visit a website containing a specially crafted EPS image binary, resulting in execution of arbitrary code in the context of the current user. (CVE-2015-2545)
