Synopsis

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

Description

The Microsoft Office application, Office Web Apps, or SharePoint Server installed on the remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in Microsoft Office software due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted Office document, to execute arbitrary code in the context of the current user. (CVE-2017-0254)

- A cross-site scripting (XSS) vulnerability exists in Microsoft SharePoint Server due improper validation of user-supplied input in web requests. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-0255)

- A remote code execution vulnerability exists in Microsoft Office due to improper handling of malformed graphics images. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted EPS file, to execute arbitrary code in the context of the current user. (CVE-2017-0261)

- A remote code execution vulnerability exists in Microsoft Office when handling malformed graphics images. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted EPS file or visit a specially crafted website, to execute arbitrary code. (CVE-2017-0262)

- A remote code execution vulnerability exists in Microsoft Office due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary code in the context of the current user. (CVE-2017-0281)
