Buffer overflow in the CallHTMLHelp method in the Microsoft Windows Media Services ActiveX control in nskey.dll 4.1.00.3917 in Windows Media Services on Microsoft Windows NT and 2000, and Avaya Media and Message Application servers, allows remote attackers to execute arbitrary code via a long argument. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Stack-based buffer overflow in Microsoft msjet40.dll 4.0.8618.0 (aka Microsoft Jet Engine), as used by Access 2003 in Microsoft Office 2003 SP3, allows user-assisted attackers to execute arbitrary code via a crafted MDB file database file containing a column structure with a modified column count. NOTE: this might be the same issue as CVE-2005-0944.

Race condition in the Virtual DOS Machine (VDM) in the Windows Kernel in Microsoft Windows NT 4.0 allows local users to modify memory and gain privileges via the temporary \Device\PhysicalMemory section handle, a related issue to CVE-2007-1206.

Microsoft Distributed Transaction Coordinator (MSDTC) for Windows NT 4.0, 2000 SP4, XP SP1 and SP2, and Server 2003 allows remote attackers to cause a denial of service (crash) via a BuildContextW request with a large (1) UuidString or (2) GuidIn of a certain length, which causes an out-of-range memory access, aka the MSDTC Denial of Service Vulnerability. NOTE: this is a variant of CVE-2005-2119.

The default configuration of the DNS Server service on Windows Server 2003 and Windows 2000, and the Microsoft DNS Server service on Windows NT 4.0, allows recursive queries and provides additional delegation information to arbitrary IP addresses, which allows remote attackers to cause a denial of service (traffic amplification) via DNS queries with spoofed source IP addresses.

Heap-based buffer overflow in the CRpcIoManagerServer::BuildContext function in msdtcprx.dll for Microsoft Distributed Transaction Coordinator (MSDTC) for Windows NT 4.0 and Windows 2000 SP2 and SP3 allows remote attackers to execute arbitrary code via a long fifth argument to the BuildContextW or BuildContext opcode, which triggers a bug in the NdrAllocate function, aka the MSDTC Invalid Memory Access Vulnerability.

Heap-based buffer overflow in T2EMBED.DLL in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 up to SP1, Windows 98, and Windows ME allows remote attackers to execute arbitrary code via an e-mail message or web page with a crafted Embedded Open Type (EOT) web font that triggers the overflow during decompression.

The thread termination routine in the kernel for Windows NT 4.0 and 2000 (NTOSKRNL.EXE) allows local users to modify kernel memory and execution flow via steps in which a terminating thread causes Asynchronous Procedure Call (APC) entries to free the wrong data, aka the "Windows Kernel 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.

The DHCP Server service for Microsoft Windows NT 4.0 Server and Terminal Server Edition does not properly validate the length of certain messages, which allows remote attackers to execute arbitrary code via a malformed DHCP message, aka the "DHCP Request Vulnerability."

The DHCP Server service for Microsoft Windows NT 4.0 Server and Terminal Server Edition, with DHCP logging enabled, does not properly validate the length of certain messages, which allows remote attackers to cause a denial of service (application crash) via a malformed DHCP message, aka "Logging Vulnerability."

The RPC Runtime Library for Microsoft Windows NT 4.0 allows remote attackers to read active memory or cause a denial of service (system crash) via a malicious message, possibly related to improper length values.

HyperTerminal application for Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 does not properly validate the length of a value that is saved in a session file, which allows remote attackers to execute arbitrary code via a malicious HyperTerminal session file (.ht), web site, or Telnet URL contained in an e-mail message, triggering a buffer overflow.

The Virtual DOS Machine (VDM) subsystem of Microsoft Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows local users to access kernel memory and gain privileges via a malicious program that modified some system structures in a way that is not properly validated by privileged operating system functions.

"Shatter" style vulnerability in the Window Management application programming interface (API) for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows local users to gain privileges by using certain API functions to change properties of privileged programs using the SetWindowLong and SetWIndowLongPtr API functions.

Network Dynamic Data Exchange (NetDDE) services for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows attackers to remotely execute arbitrary code or locally gain privileges via a malicious message or application that involves an "unchecked buffer," possibly a buffer overflow.

The DCOM RPC interface for Microsoft Windows NT 4.0, 2000, XP, and Server 2003 allows remote attackers to cause network communications via an "alter context" call that contains additional data, aka the "Object Identity Vulnerability."

Double free vulnerability in the ASN.1 library as used in Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003, allows remote attackers to cause a denial of service and possibly execute arbitrary code.

The component for the Virtual DOS Machine (VDM) subsystem in Windows NT 4.0 and Windows 2000 does not properly validate system structures, which allows local users to access protected kernel memory and execute arbitrary code.

Buffer overflow in cmd.exe in Windows NT 4.0 may allow local users to execute arbitrary code via a long pathname argument to the cd command.

The NtSetLdtEntries function in the programming interface for the Local Descriptor Table (LDT) in Windows NT 4.0 and Windows 2000 allows local attackers to gain access to kernel memory and execute arbitrary code via an expand-down data segment descriptor descriptor that points to protected memory.

The logging capability for unicast and multicast transmissions in the ISAPI extension for Microsoft Windows Media Services in Microsoft Windows NT 4.0 and 2000, nsiislog.dll, allows remote attackers to cause a denial of service in Internet Information Server (IIS) and execute arbitrary code via a certain network request.

NT Virtual DOS Machine (NTVDM.EXE) in Windows 2000, NT and XP does not verify user execution permissions for 16-bit executable files, which allows local users to bypass the loader and execute arbitrary programs.

Cross-site scripting (XSS) vulnerability in the default ASP pages on Microsoft Site Server 3.0 on Windows NT 4.0 allows remote attackers to inject arbitrary web script or HTML via the (1) ctr parameter in Default.asp and (2) the query string to formslogin.asp.

Microsoft Windows 98 and Windows NT 4.0 do not properly verify the Basic Constraints of digital certificates, allowing remote attackers to execute code, aka "New Variant of Certificate Validation Flaw Could Enable Identity Spoofing" (CAN-2002-0862).
