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."
Buffer overflow in Microsoft Internet Explorer and Explorer on Windows XP SP1, WIndows 2000, Windows 98, and Windows Me may allow remote malicious servers to cause a denial of service (application crash) and possibly execute arbitrary code via long share names, as demonstrated using Samba.
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.
The SMTP (Simple Mail Transfer Protocol) component of Microsoft Windows XP 64-bit Edition, Windows Server 2003, Windows Server 2003 64-bit Edition, and the Exchange Routing Engine component of Exchange Server 2003, allows remote attackers to execute arbitrary code via a malicious DNS response message containing length values that are not properly validated.
The WAV file property handler in Windows XP SP1 allows remote attackers to cause a denial of service (infinite loop in Explorer) via a WAV file with an invalid file header whose fmt chunk length is set to 0xFFFFFFFF.
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.
TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.
