Unspecified vulnerability in Windows 2000 Advanced Server SP4 running Active Directory allows remote attackers to cause a denial of service via unknown vectors, as demonstrated by a certain VulnDisco Pack module. NOTE: the provenance of this information is unknown; the details are obtained from third party information. As of 20061116, this disclosure has no actionable information. However, since the VulnDisco Pack author is a reliable researcher, the disclosure is being assigned a CVE identifier for tracking purposes.

Windows NT 4.0 and Windows 2000 hosts allow remote attackers to cause a denial of service (unavailable connections) by sending multiple SMB SMBnegprots requests but not reading the response that is sent back.

Web Extender Client (WEC) in Microsoft Office 2000, Windows 2000, and Windows Me does not properly process Internet Explorer security settings for NTLM authentication, which allows attackers to obtain NTLM credentials and possibly obtain the password, aka the "Web Client NTLM Authentication" vulnerability.

Format string vulnerability in the C runtime functions in SQL Server 7.0 and 2000 allows attackers to cause a denial of service.

Microsoft Windows 2000 telnet service allows attackers to prevent idle Telnet sessions from timing out, causing a denial of service by creating a large number of idle sessions.

Unknown vulnerability in the Certificate Enrollment ActiveX Control in Microsoft Windows 98, Windows 98 Second Edition, Windows Millennium, Windows NT 4.0, Windows 2000, and Windows XP allow remote attackers to delete digital certificates on a user's system via HTML.

A Windows NT account policy has inappropriate, security-critical settings for lockout, e.g. lockout duration, lockout after bad logon attempts, etc.

The default configuration of ColdFusion MX has the "Enable Robust Exception Information" option selected, which allows remote attackers to obtain the full path of the web server via a direct request to CFIDE/probe.cfm, which leaks the path in an error message.

Handle leak in Microsoft Windows 2000 telnet service allows attackers to cause a denial of service by starting a large number of sessions and terminating them.

NTMail 5.x allows network users to bypass the NTMail proxy restrictions by redirecting their requests to NTMail's web configuration server.

The SMB signing capability in the Server Message Block (SMB) protocol in Microsoft Windows 2000 and Windows XP allows attackers to disable the digital signing settings in an SMB session to force the data to be sent unsigned, then inject data into the session without detection, e.g. by modifying group policy information sent from a domain controller.

The WideCharToMultiByte function in Microsoft Windows 2000 before Update Rollup 1 for SP4 does not properly convert strings with Japanese composite characters in the last character, which could prevent the string from being null terminated and lead to data corruption or enable buffer overflow attacks.

The GetStringAMSHandler function in prgxhndl.dll in hndlrsvc.exe in the Intel Alert Handler service (aka Symantec Intel Handler service) in Intel Alert Management System (AMS), as used in Symantec Antivirus Corporate Edition 10.1.4.4010 on Windows 2000 SP4 and Symantec Endpoint Protection before 11.x, does not properly validate the CommandLine field of an AMS request, which allows remote attackers to cause a denial of service (application crash) via a crafted request.

Microsoft Windows 2000 before Update Rollup 1 for SP4, when the "audit directory service access" policy is enabled, does not record a 565 event message for File Delete Child operations on an Active Directory object in the security event log, which could allow attackers to conduct unauthorized activities without detection.

NOTE: this issue has been disputed by third parties. Microsoft Windows XP, 2000, and 2003 allows local users to kill a writable process by using the CreateRemoteThread function with certain arguments on a process that has been opened using the OpenProcess function, possibly involving an invalid address for the start routine. NOTE: followup posts have disputed this issue, saying that if a user already has privileges to write to a process, then other functions could be called or the process could be terminated using PROCESS_TERMINATE

The SfnINSTRING function in win32k.sys in the kernel in Microsoft Windows 2000, XP, and Server 2003 allows local users to cause a denial of service (system crash) via a 0x18d value in the second argument (aka the Msg argument) of a PostMessage function call for the DDEMLEvent window.

The SfnLOGONNOTIFY function in win32k.sys in the kernel in Microsoft Windows 2000, XP, and Server 2003 allows local users to cause a denial of service (system crash) via a 0x4c value in the second argument (aka the Msg argument) of a PostMessage function call for the DDEMLEvent window.

The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 does not properly validate a registry-key argument to an unspecified system call, which allows local users to cause a denial of service (reboot) via a crafted application, aka "Windows Kernel Null Pointer Vulnerability."
