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 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 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.

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.

Double free vulnerability in Microsoft Windows 2000, XP, 2003, and Vista allows local users to gain privileges by calling the MessageBox function with a MBSERVICENOTIFICATION message with crafted data, which sends a HardError message to Client/Server Runtime Server Subsystem (CSRSS) process, which is not properly handled when invoking the UserHardError and GetHardErrorText functions in WINSRV.DLL.

Microsoft Windows 2000 before Service Pack 2 (SP2), when running in a non-Windows 2000 domain and using NTLM authentication, and when credentials of an account are locally cached, allows local users to bypass account lockout policies and make an unlimited number of login attempts, aka the "Domain Account Lockout" vulnerability.

Memory leak in the SNMP LAN Manager (LANMAN) MIB extension for Microsoft Windows 2000 before SP3, when the Print Spooler is not running, allows remote attackers to cause a denial of service (memory consumption) via a large number of GET or GETNEXT requests.

Windows 2000 allows local users to cause a denial of service and possibly gain privileges by setting a hardware breakpoint that is handled using global debug registers, which could cause other processes to terminate due to an exception, and allow hijacking of resources such as named pipes.

Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.

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.

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.

Two vulnerabilities in Microsoft Virtual Machine (VM) up to and including build 5.0.3805, as used in Internet Explorer and other applications, allow remote attackers to read files via a Java applet with a spoofed location in the CODEBASE parameter in the APPLET tag, possibly due to a parsing error.

NetDDE Agent on Windows NT 4.0, 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows local users to execute arbitrary code as LocalSystem via "shatter" style attack by sending a WMCOPYDATA message followed by a WMTIMER message, as demonstrated by GetAd, aka "Flaw in Windows WMTIMER Message Handling Could Enable Privilege Elevation."

Microsoft Virtual Machine (VM) build 5.0.3805 and earlier allows remote attackers to determine a local user's username via a Java applet that accesses the user.dir system property, aka "User.dir Exposure Vulnerability."

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 system root folder of Microsoft Windows 2000 has default permissions of Everyone group with Full access (Everyone:F) and is in the search path when locating programs during login or application launch from the desktop, which could allow attackers to gain privileges as other users via Trojan horse programs.

Remote Data Protocol (RDP) version 5.0 in Microsoft Windows 2000 and RDP 5.1 in Windows XP does not encrypt the checksums of plaintext session data, which could allow a remote attacker to determine the contents of encrypted sessions via sniffing, aka "Weak Encryption in RDP Protocol."

The Remote Data Protocol (RDP) version 5.1 in Microsoft Windows XP allows remote attackers to cause a denial of service (crash) when Remote Desktop is enabled via a PDU Confirm Active data packet that does not set the Pattern BLT command, aka "Denial of Service in Remote Desktop."

NTFS file system in Windows NT 4.0 and Windows 2000 SP2 allows local attackers to hide file usage activities via a hard link to the target file, which causes the link to be recorded in the audit trail instead of the target file.

LANMAN service on Microsoft Windows 2000 allows remote attackers to cause a denial of service (CPU/memory exhaustion) via a stream of malformed data to microsoft-ds port 445.

Microsoft Windows 2000 allows local users to bypass the policy that prohibits reusing old passwords by changing the current password before it expires, which does not enable the check for previous passwords.

The MSDTC (Microsoft Distributed Transaction Service Coordinator) for Microsoft Windows 2000, Microsoft IIS 5.0 and SQL Server 6.5 through SQL 2000 0.0 allows remote attackers to cause a denial of service (crash or hang) via malformed (random) input.
