default, all supported versions of Microsoft Outlook, Microsoft Outlook
Express, and Windows Mail open HTML email messages in the Restricted sites
zone. The Restricted sites zone, which disables script and ActiveX controls,
helps reduce the risk of an attacker being able to use this vulnerability to
execute malicious code. If a user clicks a link in an email message, the user
could still be vulnerable to exploitation of this vulnerability through the
web-based attack scenario.

·        
By
default, Internet Explorer on Windows Server 2003, Windows Server 2008, and
Windows Server 2008 R2 runs in a restricted mode that is known as Enhanced
Security Configuration. This mode mitigates this vulnerability.

·        
In
a web-based attack scenario, an attacker would have to convince users to
visit the website, typically by getting them to click a link in an email
message or Instant Messenger message that takes users to the attacker’s
website, and convince them to open the 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
