Synopsis

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

Description

The Microsoft Office Online Server or SharePoint Server 2010 Office Web Apps 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.

Solution

Microsoft has released a set of patches for Microsoft Office Online Server and SharePoint Server 2010 Office Web Apps.
