Bulletin Identifier: Microsoft Security Bulletin MS08-014
Bulletin Title: Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (949029)
Executive Summary: This security update resolves several privately reported and publicly reported vulnerabilities in Microsoft Office Excel that could allow remote code execution if a user opens a specially crafted Excel file. An attacker who successfully exploited these vulnerabilities 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 impacted than users who operate with administrative user rights.
Maximum Severity Rating: Critical
Impact of Vulnerability: Remote Code Execution
Detection: Microsoft Baseline Security Analyzer can detect whether your computer system requires this update. The update will not require a restart.
Affected Software: Microsoft Office. For more information, see the Affected Software and Download Locations section.

Bulletin Identifier: Microsoft Security Bulletin MS08-015
Bulletin Title: Vulnerability in Microsoft Outlook Could Allow Remote Code Execution (949031)
Executive Summary: 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.
