The local and remote desktop login screens in Microsoft Windows XP before SP2 and 2003 allow remote attackers to cause a denial of service (CPU and memory consumption) by repeatedly using the WinKey+"U" key combination, which causes multiple copies of Windows Utility Manager to be loaded more quickly than they can be closed when the copies detect that another instance is running.

The Windows Animated Cursor (ANI) capability in Windows NT, Windows 2000 through SP4, Windows XP through SP1, and Windows 2003 allow remote attackers to cause a denial of service via (1) the frame number set to zero, which causes an invalid memory address to be used and leads to a kernel crash, or (2) the rate number set to zero, which leads to resource exhaustion and hang.

Integer underflow in winhlp32.exe in Windows NT, Windows 2000 through SP4, Windows XP through SP2, and Windows 2003 allows remote attackers to execute arbitrary code via a malformed .hlp file, which leads to a heap-based buffer overflow.

The DHTML Edit Control (dhtmled.ocx) allows remote attackers to inject arbitrary web script into other domains by setting a name for a window, opening a child page whose target is the window with the given name, then injecting the script from the parent into the child using execScript, as demonstrated by "AbusiveParent" in Internet Explorer 6.0.2900.2180.

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.

"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.

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.

Unknown vulnerability in the Graphics Rendering Engine processes of Microsoft Windows 2000, Windows XP, and Windows Server 2003 allows remote attackers to execute arbitrary code via (1) Windows Metafile (WMF) or (2) Enhanced Metafile (EMF) image formats that involve "an unchecked buffer."

The kernel for Microsoft Windows Server 2003 does not reset certain values in CPU data structures, which allows local users to cause a denial of service (system crash) via a malicious program.

Integer overflow in DUNZIP32.DLL for Microsoft Windows XP, Windows XP 64-bit Edition, Windows Server 2003, and Windows Server 2003 64-bit Edition allows remote attackers to execute arbitrary code via compressed (zipped) folders that involve an "unchecked buffer" and improper length validation.

Buffer overflow in the JPEG (JPG) parsing engine in the Microsoft Graphic Device Interface Plus (GDI+) component, GDIPlus.dll, allows remote attackers to execute arbitrary code via a JPEG image with a small JPEG COM field length that is normalized to a large integer length before a memory copy operation.

Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html".

Heap-based buffer overflow in the HtmlHelp program (hh.exe) in HTML Help for Microsoft Windows 98, Me, NT 4.0, 2000, XP, and Server 2003 allows remote attackers to execute arbitrary commands via a .CHM file with a large length field, a different vulnerability than CVE-2003-1041.

IDirectPlay4 Application Programming Interface (API) of Microsoft DirectPlay 7.0a thru 9.0b, as used in Windows Server 2003 and earlier allows remote attackers to cause a denial of service (application crash) via a malformed packet.

Help and Support Center in Microsoft Windows XP and Windows Server 2003 SP1 does not properly validate HCP URLs, which allows remote attackers to execute arbitrary code, as demonstrated using certain hcp:// URLs that access the DVD Upgrade capability (dvdupgrd.htm).

Stack-based buffer overflow in certain Active Directory service functions in LSASRV.DLL of the Local Security Authority Subsystem Service (LSASS) in Microsoft Windows NT 4.0 SP6a, 2000 SP2 through SP4, XP SP1, Server 2003, NetMeeting, Windows 98, and Windows ME, allows remote attackers to execute arbitrary code via a packet that causes the DsRolerUpgradeDownlevelServer function to create long debug entries for the DCPROMO.LOG log file, as exploited by the Sasser worm.

Buffer overflow in the Private Communications Transport (PCT) protocol implementation in the Microsoft SSL library, as used in Microsoft Windows NT 4.0 SP6a, 2000 SP2 through SP4, XP SP1, Server 2003, NetMeeting, Windows 98, and Windows ME, allows remote attackers to execute arbitrary code via PCT 1.0 handshake packets.

Buffer overflow in the COM Internet Services and in the RPC over HTTP Proxy components for Microsoft Windows NT Server 4.0, NT 4.0 Terminal Server Edition, 2000, XP, and Server 2003 allows remote attackers to cause a denial of service via a crafted request.

Help and Support Center in Microsoft Windows XP SP1 does not properly validate HCP URLs, which allows remote attackers to execute arbitrary code via quotation marks in an hcp:// URL, which are not quoted when constructing the argument list to HelpCtr.exe.

An Activation function in the RPCSS Service involved with DCOM activation for Microsoft Windows 2000, XP, and 2003 allows remote attackers to cause a denial of service (memory consumption) via an activation request with a large length field.
