SUMMARY

Microsoft distributes SQL Server 2000 security fixes as one downloadable file. Because the security fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 security fix release. You do not have to install a previous security patch before you install the latest one.

INTRODUCTION

This Microsoft Knowledge Base article contains a list of all the security fixes that are available for SQL Server 2000 Service Pack 3 (SP3), SQL Server 2000 Service Pack 3a (SP3a), SQL Server 2000 Desktop Engine (MSDE) Service Pack 3 (SP3), and SQL Server 2000 Desktop Engine (MSDE) Service Pack 3a (SP3a).

Important notes

This cumulative package does not contain the security fixes that are in Microsoft Data Access Components (MDAC) and Analysis Services.

Here is a list of the vulnerabilities that are resolved by this security patch:

Named Pipe Hijacking
When SQL Server starts, it creates and then listens on a specific named pipe for incoming connections to the server. A named pipe is a specifically named one-way or two-way channel for communication between a pipe server and one or more pipe clients. SQL Server checks the named pipe to verify what connections can log on to the system that is running SQL Server to run queries against data that is stored on the server.

A flaw exists in the checking method for the named pipe that might allow an attacker who is local to the system that is running SQL Server to hijack (gain control of) the named pipe when another client uses an authenticated logon password to logon. This would allow the attacker to gain control of the named pipe at the same permission level as the user who is trying to connect. If the user who is trying to connect remotely has a higher level of permissions than the attacker does, the attacker will assume those rights when the named pipe is compromised.
Named Pipe Denial of Service
In the same named pipes scenario that is mentioned in the "Named Pipe Hijacking" section of this article, an unauthenticated user who is local to the intranet might be able to send a very large packet to a specific named pipe where the system running SQL Server is listening and cause it to become unresponsive.

This vulnerability does not allow an attacker to run arbitrary code or elevate their permissions; however, a denial of service condition might still exist that requires you to restart the server to restore functionality.
SQL Server Buffer Overrun
A flaw exists in a specific Windows function that may allow an authenticated user who has direct access to log on to the system running SQL Server the ability to create a specially crafted packet that when sent to the listening local procedure call (LPC) port of the system, can cause a buffer overrun. If successfully exploited, this can allow a user who has limited permissions on the system to elevate their permissions to the level of the SQL Server service account, or cause arbitrary code to run.

SQL Server prompts you for a password after you install MS03-031: Cumulative security patch for SQL Server

After you install "MS03-031: Cumulative Security Patch for SQL Server", when you make changes to a standard SQL Server login by using Enterprise Manager, SQL Server prompts you for a password, even if you did not change the password. If you did not change the password, you cannot successfully close the dialog box, regardless of the entry that you use. To resolve or avoid this problem, download and use the fix that is in the following Microsoft Knowledge Base article:

Important notes

Read these important notes about the installation of this patch on a computer that is running SQL Server 2000 SP3.

Universal Description, Discovery, and Integration (UDDI) services

If you install this security patch on a computer that is running Microsoft Windows Server 2003, and UDDI Services is installed, you must take one of two actions to restart UDDI Services, depending on your circumstances. The UDDI Services will not resume normal functioning until you do.

If no other Web service is in use on the computer that is running Windows Server 2003, you can restart the UDDI Services by restarting Microsoft Internet Information Services (IIS). Restarting IIS is the same as first stopping IIS, and then starting it again, except it is done with a single command. There are two ways to restart IIS:
- Use the IIS Manager graphical user interface.
- Use the IISReset command-line utility.
If other Web services are in use on the computer that is running Windows Server 2003, you may not want to affect their operation. To restart the UDDI Services, follow these steps:
1. Start the IIS Manager utility.
2. Locate the Application Pools folder, and then right-click the MSUDDIAppPool icon.
3. Click to select the Recycle menu option. Doing so will allow UDDI Services to resume operation without affecting any other Web service on the computer.

An error message occurs when you connect to a Microsoft Windows NT 4.0-based computer by using named pipes

When you connect to a Windows NT 4.0-based computer that is running Microsoft SQL Server 2000 by using named pipes, and that connection is made by a non-admin user, you may receive an error message similar to one of the following:

Message 1

Connection could not be established. SQL Server does not exist

Message 2

Connection could not be established. Access is denied.

To obtain a hotfix to resolve this error message, see the following article in the Microsoft Knowledge Base:

Installation information

This security patch supports the following Setup switches.

Collapse this tableExpand this table

Switch	Description
s	Disables the Self Extraction progress dialog box. Must come before the /a switch.
/a	This parameter must come before all parameters except /s if you are running the hotfix by using the self-extracting EXE, and you want to include parameters for unattended installations. This is a mandatory parameter for the installer to run in the unattended mode.
/q	This switch causes the Setup program to run in silent mode with no user interface.
INSTANCENAME	Name of the instance of SQL Server. You must enter it as follows: INSTANCENAME=`yourinstancename`
BLANKSAPWD	Means a blank sa password for SQL Authentication. If you enter this parameter on computers that are running Microsoft Windows NT or Microsoft Windows 2000, the default Windows Authentication logon is overridden and it tries to log on with a blank sa password. The correct format for this parameter is BLANKSAPWD=1. This parameter is recognized only for unattended installations.
SAPWD	Non-blank sa password. If you enter this parameter, it must be in the form of SAPWD=`yoursapassword`. This parameter overrides the default Windows Authentication on computers that are running Windows NT or Windows 2000, or BLANKSAPWD, if entered.
