Vulnerability Information

Visio Viewer Tree Object Type Confusion Vulnerability - CVE-2013-0079

A remote code execution vulnerability exists in the way that Microsoft Visio
Viewer handles memory when rendering specially crafted Visio files. An attacker
who successfully exploited this vulnerability could take complete control of an
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 affected
than users who operate with administrative user rights.
