Microsoft Agent allows remote attackers to spoof trusted Internet content and execute arbitrary code by disguising security prompts on a malicious Web page.

User32.DLL in Microsoft Windows 98SE, and possibly other operating systems, allows local and remote attackers to cause a denial of service (crash) via an icon (.ico) bitmap file with large width and height values.

Buffer overflow in the Message Queuing component of Microsoft Windows 2000 and Windows XP SP1 allows remote attackers to execute arbitrary code via a crafted message.

The TCP/IP stack in multiple operating systems allows remote attackers to cause a denial of service (CPU consumption) via a TCP packet with the correct sequence number but the wrong Acknowledgement number, which generates a large number of "keep alive" packets. NOTE: some followups indicate that this issue could not be replicated.

The Hyperlink Object Library for Windows 98, 2000, XP, and Server 2003 allows remote attackers to execute arbitrary code via a crafted link that triggers an "unchecked buffer" in the library, possibly due to a buffer overflow.

Buffer overflow in the font processing component of Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to gain privileges via a specially-designed application.

Internet Explorer 5.01, 5.5, and 6 allows remote attackers to execute arbitrary code via drag and drop events, aka the "Drag-and-Drop Vulnerability."

The kernel of Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to gain privileges via certain access requests.

The document processing application used by the Windows Shell in Microsoft Windows 2000, Windows XP, and Windows Server 2003 allows remote attackers to execute arbitrary code by modifying the CLSID stored in a file so that it is processed by HTML Application Host (MSHTA), as demonstrated using a Microsoft Word document.

The OLE component in Windows 98, 2000, XP, and Server 2003, and Exchange Server 5.0 through 2003, does not properly validate the lengths of messages for certain OLE data, which allows remote attackers to execute arbitrary code, aka the "Input Validation Vulnerability."
