This security update resolves a privately reported vulnerability in Microsoft
Office Outlook. The vulnerability could allow remote code execution if Outlook
is passed a specially crafted mailto URI. 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. This
vulnerability is not exploitable by simply viewing an e-mail through the Outlook
preview pane.
