SUMMARY

Here is a list of the vulnerabilities that are resolved in 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.

Installation Information

This 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 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.
INSTANCENAMEName of the instance of SQL Server. You must enter it as follows:

INSTANCENAME=yourinstancename
BLANKSAPWDMeans 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.
SAPWDNon-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.
