Critical

• Microsoft Security Bulletin MS07-064 --Vulnerabilities in DirectX Could Allow Remote Code Execution (941568)
  

Executive Summary: This critical security update resolves two privately reported vulnerabilities in Microsoft DirectX. These vulnerabilities could allow code execution if a user opened a specially crafted file used for streaming media in DirectX. If a user is logged on with administrative user rights, 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 impacted than users who operate with administrative user rights.

Impact of Vulnerability: Remote Code Execution
Affected Software: Windows, DirectX, DirectShow.
Restart Requirement: The update will not require a restart, except in certain situations.
Bulletins Replaced by This Update: MS05-050

• Microsoft Security Bulletin MS07-068 -- Bulletin Title: Vulnerability in Windows Media File Format Could Allow Remote Code Execution (941569 and 944275)

Executive Summary: This critical security update resolves a privately reported vulnerability in Windows Media Format. This vulnerability could allow remote code execution if a user viewed a specially crafted file in Windows Media Format Runtime. 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.

Impact of Vulnerability: Remote Code Execution
Affected Software: Windows, Windows Media Format Runtime.
Restart Requirement: The update will not require a restart, except in certain situations.
Bulletins Replaced by This Update: MS06-078

• Microsoft Security Bulletin MS07-069 -- Bulletin Title: Cumulative Security Update for Internet Explorer (942615)

This important security update resolves a privately reported vulnerability in Server Message Block Version 2 (SMBv2). The vulnerability could allow an attacker to tamper with data transferred via SMBv2, which could allow remote code execution in domain configurations communicating with SMBv2.

Impact of Vulnerability: Remote Code Execution
Affected Software: Windows.
Restart Requirement: The update will require a restart.

• Microsoft Security Bulletin MS07-065 -- Vulnerability in Message Queuing Could Allow Remote Code Execution (937894)

Executive Summary: This important security update resolves a privately reported vulnerability in Message Queuing Service (MSMQ) that could allow remote code execution in implementations on Microsoft Windows 2000 Server, or elevation of privilege in implementations on Microsoft Windows 2000 Professional and Windows XP. An attacker must have valid logon credentials to exploit this vulnerability. An attacker could then install programs; view, change, or delete data; or create new accounts.

Impact of Vulnerability: Remote Code Execution
Affected Software: Windows.
Restart Requirement: The update will require a restart.
Bulletins Replaced by This Update: MS05-017

• Microsoft Security Bulletin MS07-066 -- Bulletin Title: Vulnerability in Windows Kernel Could Allow Elevation of Privilege (943078)

Impact of Vulnerability: Elevation of Privilege
Affected Software: Windows.
Restart Requirement: The update will require a restart.

• Microsoft Security Bulletin MS07-067 -- Vulnerability in Macrovision Driver Could Allow Local Elevation of Privilege (944653)

Executive Summary: This important security update resolves one publicly disclosed vulnerability. A local elevation of privilege vulnerability exists in the way that the Macrovision driver incorrectly handles configuration parameters. An attacker who successfully exploited this vulnerability could take complete control of the system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Impact of Vulnerability: Local Elevation of Privilege
Affected Software: Windows.
