Name of the Vulnerable Software and Affected Versions Microsoft Office versions 2007 SP3 through 2016 Office Compatibility Pack version SP3 Word Viewer version (affected versions not specified) Word Automation Services on SharePoint Server version 2013 SP1 Office Web Apps Server version 2013 SP1 SharePoint Server version 2013 SP1

Description The issue is caused by a memory corruption flaw in Microsoft Office software, allowing remote attackers to execute arbitrary code via a crafted Office document. This can occur when the Office software fails to properly handle objects in memory. An attacker who successfully exploits the issue could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system, then install programs, view, change, or delete data, or create new accounts with full user rights.

Recommendations For Microsoft Office versions 2007 SP3 through 2016, update to a version that includes the fix for this issue. For Office Compatibility Pack version SP3, update to a version that includes the fix for this issue. For Word Viewer, Word Automation Services on SharePoint Server 2013 SP1, Office Web Apps Server 2013 SP1, and SharePoint Server 2013 SP1, apply the configuration changes and workarounds provided by Microsoft to mitigate the risk of exploitation until a patch is available. As a temporary workaround, consider restricting access to crafted Office documents until a patch is available.
