General Information

Executive Summary

This security update resolves a privately reported vulnerability in Microsoft 
Office. The vulnerability could allow remote code execution if a user opens a 
specially crafted Visio file. An attacker who successfully exploited this 
vulnerability could gain the same user rights as the current user. Users whose 
accounts are configured to have fewer user rights on the system could be less 
impacted than users who operate with administrative user rights.

This security update is rated Important for all supported editions of Microsoft 
Visio 2010 and Microsoft Visio Viewer 2010. For more information, see the 
subsection, Affected and Non-Affected Software, in this section.

Vulnerability Information

Visio DXF File Format Buffer Overflow Vulnerability - CVE-2012-1888

This is a remote code execution vulnerability. An attacker who successfully 
exploited this vulnerability could run arbitrary code as the current user. If
the current user is logged on with administrative user rights, an attacker 
could take complete control of the affected system. An attacker could then 
install programs; view, change, or delete data; or create new accounts with 
full user rights. Users whose accounts are configured to have fewer user 
rights on the system could be less impacted than users who operate with 
administrative user rights.
