Unknown vulnerability in the PKINIT Protocol for Microsoft Windows 2000, Windows XP, and Windows Server 2003 could allow a local user to obtain information and spoof a server via a man-in-the-middle (MITM) attack between a client and a domain controller when PKINIT smart card authentication is being used.

Stack-based buffer overflow in the Plug and Play (PnP) service for Microsoft Windows 2000 and Windows XP Service Pack 1 allows remote attackers to execute arbitrary code via a crafted packet, and local users to gain privileges via a malicious application, as exploited by the Zotob (aka Mytob) worm.

Buffer overflow in a certain USB driver, as used on Microsoft Windows, allows attackers to execute arbitrary code.

netman.dll in Microsoft Windows Connections Manager Library allows local users to cause a denial of service (Network Connections Service crash) via a large integer argument to a particular function, aka "Network Connection Manager Vulnerability."

Windows NT 4.0 and Windows 2000 before URP1 for Windows 2000 SP4 does not properly prevent NULL sessions from accessing certain alternate named pipes, which allows remote attackers to (1) list Windows services via svcctl or (2) read eventlogs via eventlog.

Buffer overflow in the Server Message Block (SMB) functionality for Microsoft Windows 2000, XP SP1 and SP2, and Server 2003 and SP1 allows remote attackers to execute arbitrary code via unknown vectors, aka the "Server Message Block Vulnerability."

Integer overflow in Microsoft Windows 98, 2000, XP SP2 and earlier, and Server 2003 SP1 and earlier allows remote attackers to execute arbitrary code via a crafted compiled Help (.CHM) file with a large size field that triggers a heap-based buffer overflow, as demonstrated using a "ms-its:" URL in Internet Explorer.

Buffer overflow in Microsoft Step-by-Step Interactive Training (orun32.exe) allows remote attackers to execute arbitrary code via a bookmark link file (.cbo, cbl, or .cbm extension) with a long User field.

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

Heap-based buffer overflow in the BERDecBitString function in Microsoft ASN.1 library (MSASN1.DLL) allows remote attackers to execute arbitrary code via nested constructed bit strings, which leads to a realloc of a non-null pointer and causes the function to overwrite previously freed memory, as demonstrated using a SPNEGO token with a constructed bit string during HTTP authentication, and a different vulnerability than CVE-2003-0818. NOTE: the researcher has claimed that MS:MS04-007 fixes this issue.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

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."

The Server Message Block (SMB) implementation for Windows NT 4.0, 2000, XP, and Server 2003 does not properly validate certain SMB packets, which allows remote attackers to execute arbitrary code via Transaction responses containing (1) Trans or (2) Trans2 commands, aka the "Server Message Block Vulnerability," and as demonstrated using Trans2 FIND_FIRST2 responses with large file name length fields.

Windows 2000, XP, and Server 2003 does not properly "validate the use of memory regions" for COM structured storage files, which allows attackers to execute arbitrary code, aka the "COM Structured Storage Vulnerability."

Microsoft Windows XP SP2 and earlier, 2000 SP3 and SP4, Server 2003, and older operating systems allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IP packets with malformed options, aka the "IP Validation Vulnerability."

The License Logging service for Windows NT Server, Windows 2000 Server, and Windows Server 2003 does not properly validate the length of messages, which leads to an "unchecked buffer" and allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, aka the "License Logging Service Vulnerability."

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

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.
