• Excel Vulnerability - CAN-2004-0846
  A remote code execution vulnerability exists in Excel. If a user is logged on with administrative privileges, an attacker who successfully exploited this vulnerability could take complete control of the affected system.

Microsoft Security Bulletin MS04-034

Vulnerability in Compressed (zipped) Folders Could Allow Remote Code Execution (873376)

Severity: Critical
Vulnerabilities:

• Compressed (zipped) Folders Vulnerability - CAN-2004-0575
  A remote code execution vulnerability exists in Compressed (zipped) Folders because of an unchecked buffer in the way that it handles specially crafted compressed files. An attacker could exploit the vulnerability by constructing a malicious compressed file that could potentially allow remote code execution if a user visited a malicious Web site. An attacker who successfully exploited this vulnerability could take complete control of an affected system. However, user interaction is required to exploit this vulnerability.

Microsoft Security Bulletin MS04-035

Vulnerability in SMTP Could Allow Remote Code Execution (885881)

Severity: Critical
Vulnerabilities:

• SMTP Vulnerability - CAN-2004-0840
  A remote code execution vulnerability exists in the Windows Server 2003 SMTP component because of the way that it handles Domain Name System (DNS) lookups. An attacker could exploit the vulnerability by causing the server to process a particular DNS response that could potentially allow remote code execution. An attacker who successfully exploited this vulnerability could take complete control of an affected system. The vulnerability also exists in the Microsoft Exchange Server 2003 Routing Engine component when installed on Microsoft Windows 2000 Service Pack 3 or on Microsoft Windows 2000 Service Pack 4.

Microsoft Security Bulletin MS04-036

Vulnerability in NNTP Could Allow Remote Code Execution (883935)

Severity: Critical
Vulnerabilities:

• NNTP Vulnerability - CAN-2004-0574
  A remote code execution vulnerability exists within the Network News Transfer Protocol (NNTP) component of the affected operating systems. This vulnerability could potentially affect systems that do not use NNTP. This is because some programs that are listed in the affected software section require that the NNTP component be enabled before you can install them. An attacker could exploit the vulnerability by constructing a malicious request that could potentially allow remote code execution. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Microsoft Security Bulletin MS04-037

Vulnerability in Windows Shell Could Allow Remote Code Execution (841356)

Severity: Critical
Vulnerabilities:

• Shell Vulnerability - CAN-2004-0214
  A remote code execution vulnerability exists in the way that the Windows Shell starts applications. An attacker could exploit the vulnerability if a user visited a malicious Web site. If a user is logged on with administrative privileges, an attacker who successfully exploited this vulnerability could take complete control of an affected system. However, user interaction is required to exploit this vulnerability.
• Program Group Converter Vulnerability - CAN-2004-0572
  A remote code execution vulnerability exists in Program Group Converter because of the way that it handles specially crafted requests. An attacker could exploit the vulnerability by constructing a malicious request that could potentially allow remote code execution if a user performed an action such as opening a file attachment or clicking a HTML link. If a user is logged on with administrative privileges, an attacker who successfully exploited this vulnerability could take complete control of an affected system. However, user interaction is required to exploit this vulnerability.
