Stack-based buffer overflow in the PCHealth system in the Help and Support Center function in Windows XP and Windows Server 2003 allows remote attackers to execute arbitrary code via a long query in an HCP URL.

A multi-threaded race condition in the Windows RPC DCOM functionality with the MS03-039 patch installed allows remote attackers to cause a denial of service (crash or reboot) by causing two threads to process the same RPC request, which causes one thread to use memory after it has been freed, a different vulnerability than CVE-2003-0352 (Blaster/Nachi), CVE-2003-0715, and CVE-2003-0528, and as demonstrated by certain exploits against those vulnerabilities.

The NetBT Name Service (NBNS) for NetBIOS in Windows NT 4.0, 2000, XP, and Server 2003 may include random memory in a response to a NBNS query, which could allow remote attackers to obtain sensitive information.

Heap-based buffer overflow in the Distributed Component Object Model (DCOM) interface in the RPCSS Service allows remote attackers to execute arbitrary code via a malformed RPC request with a long filename parameter, a different vulnerability than CVE-2003-0352 (Blaster/Nachi) and CVE-2003-0715.

Heap-based buffer overflow in the Distributed Component Object Model (DCOM) interface in the RPCSS Service allows remote attackers to execute arbitrary code via a malformed DCERPC DCOM object activation request packet with modified length fields, a different vulnerability than CVE-2003-0352 (Blaster/Nachi) and CVE-2003-0528.

Buffer overflow in a certain DCOM interface for RPC in Microsoft Windows NT 4.0, 2000, XP, and Server 2003 allows remote attackers to execute arbitrary code via a malformed message, as exploited by the Blaster/MSblast/LovSAN and Nachi/Welchia worms.

Buffer overflow in the SMB capability for Microsoft Windows XP, 2000, and NT allows remote attackers to cause a denial of service and possibly execute arbitrary code via an SMB packet that specifies a smaller buffer length than is required.

Buffer overflow in the HTML Converter (HTML32.cnv) on various Windows operating systems allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via cut-and-paste operation, as demonstrated in Internet Explorer 5.0 using a long "align" argument in an HR tag.

Buffer overflow in Windows Kernel allows local users to gain privileges by causing certain error messages to be passed to a debugger.

The RPC component in Windows 2000, Windows NT 4.0, and Windows XP allows remote attackers to cause a denial of service (disabled RPC service) via a malformed packet to the RPC Endpoint Mapper at TCP port 135, which triggers a null pointer dereference.
