Vulnerabilidades

The control for listing accessibility options in the Accessibility Utility Manager on Windows 2000 (ListView) does not properly handle Windows messages, which allows local users to execute arbitrary code via a "Shatter" style message to the Utility Manager that references a user-controlled callback function.

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.

Microsoft SQL Server before Windows 2000 SP4 allows local users to gain privileges as the SQL Server user by calling the xp_fileexist extended stored procedure with a named pipe as an argument instead of a normal file.

Stack-based buffer overflow in Active Directory in Windows 2000 before SP4 allows remote attackers to cause a denial of service (reboot) and possibly execute arbitrary code via an LDAP version 3 search request with a large number of (1) "AND," (2) "OR," and possibly other statements, which causes LSASS.EXE to crash.

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 the ShellExecute API function of SHELL32.DLL in Windows 2000 before SP4 may allow attackers to cause a denial of service or execute arbitrary code via a long third argument.

Buffer overflow in the streaming media component for logging multicast requests in the ISAPI for the logging capability of Microsoft Windows Media Services (nsiislog.dll), as installed in IIS 5.0, allows remote attackers to execute arbitrary code via a large POST request to nsiislog.dll.

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…

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

The ByteCode Verifier component of Microsoft Virtual Machine (VM) build 5.0.3809 and earlier, as used in Windows and Internet Explorer, allows remote attackers to bypass security checks and execute arbitrary code via a malicious Java applet, aka "Flaw in Microsoft VM Could Enable System Compromise."

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.

Buffer overflow in ntdll.dll on Microsoft Windows NT 4.0, Windows NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows remote attackers to execute arbitrary code, as demonstrated via a WebDAV request to IIS 5.0.

Integer overflow in JsArrayFunctionHeapSort function used by Windows Script Engine for JScript (JScript.dll) on various Windows operating system allows remote attackers to execute arbitrary code via a malicious web page or HTML e-mail that uses a large array index value that enables a heap-based buffer overflow attack.

Buffer overflow in the RPC Locator service for Microsoft Windows NT 4.0, Windows NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows local users to execute arbitrary code via an RPC call to the service containing certain parameter information.

Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets, as demonstrated by Etherleak.

Microsoft Windows XP and Windows 2000, when configured to send administrative alerts and the "Do not overwrite events (clear log manually)" option is set, does not notify the administrator when the log reaches its maximum size, which allows local users and remote attackers to avoid detection.

Windows File Protection (WFP) in Windows 2000 and XP does not remove old security catalog .CAT files, which could allow local users to replace new files with vulnerable old files that have valid hash codes.

Cross-site scripting vulnerability (XSS) in the missing template handler in Macromedia ColdFusion MX allows remote attackers to execute arbitrary script as other users by injecting script into the HTTP request for the name of a template, which is not filtered in the resulting 404 error message.

Active Directory in Windows 2000, when supporting Kerberos V authentication and GSSAPI, allows remote attackers to cause a denial of service (hang) via an LDAP client that sets the page length to zero during a large request.

The terminal services screensaver for Microsoft Windows 2000 does not automatically lock the terminal window if the window is minimized, which could allow local users to gain access to the terminal server window.

The screensaver on Windows NT 4.0, 2000, XP, and 2002 does not verify if a domain account has already been locked when a valid password is provided, which makes it easier for users with physical access to conduct brute force password guessing.

The DCOM client in Windows 2000 before SP3 does not properly clear memory before sending an "alter context" request, which may allow remote attackers to obtain sensitive information by sniffing the session.

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.

Microsoft Windows 2000 allows remote attackers to cause a denial of service (memory consumption) by sending a flood of empty TCP/IP packets with the ACK and FIN bits set to the NetBIOS port (TCP/139), as demonstrated by stream3.
