Attack Vectors
A maliciously crafted webpage.
A maliciously crafted HTML email.
Mitigating Factors
Users would have to be persuaded to visit a malicious website.
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.
Exploitation only gains the same user rights as the logged-on account.
By default, IE on Windows 2003, Windows Server 2008, and Windows Server 2008 R2 runs in a restricted mode.
By default, all versions of Outlook, Outlook Express, and Windows Mail open HTML email messages in the Restricted Sites zone.
Restart Requirement This update requires a restart.
