SUMMARY

This Microsoft Knowledge Base article contains information about the release of a SQL Server 7.0 Service Pack 4 (SP4) and Microsoft Data Engine 1.0 SP4 security patch. This security patch supersedes all previous security patches that are documented in the following Microsoft Knowledge Base article, including the security patch for Microsoft Security Bulletin MS02-061 for SQL Server 7.0:
327068  (http://support.microsoft.com/kb/327068/ ) SQL Server 7.0 security update for Service Pack 4

Important notes

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

This security patch resolves the following vulnerabilities:
  • 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 bulletin, it is possible for an unauthenticated user who is local to the intranet to send a very large packet to a specific named pipe where the computer running SQL Server is listening and cause it to become unresponsive.

    This vulnerability would not allow an attacker to run arbitrary code or elevate their permissions, but it may still be possible for a denial of service condition to exist that would require that the server be restarted 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.

MORE INFORMATION

Important notes

Read the following important notes about installing this security patch on a computer that is running SQL Server 7.0 SP4.

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 SQL Server 7.0 by using named pipes, and that connection is made by a non-admin user, you may receive an error message that is 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:
823492  (http://support.microsoft.com/kb/823492/ ) "Connection could not be established" error message when you connect to a Windows NT 4.0-based computer that is running SQL Server 2000 or SQL Server 7.0

Prerequisites

This security patch requires SQL Server 7.0 SP4.

301511  (http://support.microsoft.com/kb/301511/ ) How to obtain the latest SQL Server 7.0 service pack
For clustered SQL Server 7.0 installations, you must first uncluster SQL Server by running the SQL Server Failover Wizard from the primary cluster node of each virtual SQL Server.
Active/Active
Follow these steps for an Active/Active installation:
  1. Make sure that the computer node where SQL Server 7.0 was originally installed controls both the SQL Server resource groups.
  2. On each node of the cluster, run the Failover Setup Wizard utility to remove that virtual SQL Server.
  3. After you uncluster SQL Server, you must run the hotfix executable file on both the nodes, and complete the hotfix installation successfully before you re-cluster SQL Server.
Active/Passive
Follow these steps for an Active/Passive installation:
  1. Make sure that the computer node where SQL Server 7.0 was originally installed controls the SQL Server resources.
  2. On this same computer node, run the Failover Setup Wizard utility to remove that virtual SQL Server.
  3. After you uncluster SQL Server, you must run the hotfix executable file on the primary node only, and complete the hotfix installation successfully before you re-cluster SQL Server.

Installation information

This security patch supports the following Setup switches.
Collapse this tableExpand this table
SwitchDescription
/sDisables the Self Extraction progress dialog box. Must come before the /a switch.
/aThis parameter must come before all the other 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.
/qThis switch causes the Setup program to run in silent mode with no user interface.
BLANKSAPWD This parameter means that the sa password for SQL Authentication is blank. If you enter this parameter on computers that are running Windows NT or 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.
SAPWDNon-blank sa password. If you enter this parameter, it must be in the form of SAPWD=yoursapassword. This parameter overrides default Windows Authentication on computers that are running Windows NT or Windows 2000, or BLANKSAPWD, if entered.
