Version: 1.1
General Information
Executive Summary
This security update resolves three privately reported vulnerabilities in Windows Print Spooler. The most severe vulnerability could allow remote code execution if an affected server received a specially crafted RPC request. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.
This security update is rated Critical for all supported editions of Microsoft Windows 2000; Moderate for all supported editions of Windows XP and Windows Server 2003; and Important for all supported editions of Windows Vista and Windows Server 2008. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The update addresses the vulnerabilities by changing the way the print spooler parses certain printing data structures, limiting the location where separator pages or embedded files can be read by the Windows Printing Service, and restricting the paths from which the print spooler can load a DLL. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Buffer Overflow in Print Spooler Vulnerability - CVE-2009-0228
A remote code execution vulnerability exists in the Windows Print Spooler that could allow a remote, unauthenticated attacker to execute arbitrary code on an affected system. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2009-0228.
Mitigating Factors for Buffer Overflow in Print Spooler Vulnerability - CVE-2009-0228
Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:
- Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.
Workarounds for Buffer Overflow in Print Spooler Vulnerability - CVE-2009-0228
Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:
Block TCP ports 139 and 445 at the firewall
These ports are used to initiate a connection with the affected component. Blocking TCP ports 139 and 445 at the firewall will help protect systems that are behind that firewall from attempts to exploit this vulnerability. Microsoft recommends that you block all unsolicited inbound communication from the Internet to help prevent attacks that may use other ports. For more information about ports, see TCP and UDP Port Assignments.
Impact of workaround. Several Windows services use the affected ports. Blocking connectivity to the ports may cause various applications or services to not function. Some of the applications or services that could be impacted are listed below:
- Applications that use SMB (CIFS)
- Applications that use mailslots or named pipes (RPC over SMB)
- Server (File and Print Sharing)
- Group Policy
- Net Logon
- Distributed File System (DFS)
- Terminal Server Licensing
- Print Spooler
- Computer Browser
- Remote Procedure Call Locator
- Fax Service
- Indexing Service
- Performance Logs and Alerts
- Systems Management Server
- License Logging Service
On Microsoft Windows 2000 Server Service Pack 4, remove the Print Spooler service from the NullSessionPipes registry key
Microsoft Windows 2000 Server Service Pack 4 allows anonymous connections to the affected service. To help prevent attempts to exploit this vulnerability by anonymous attackers, remove the Print Spooler Service from the NullSessionPipes subkey. This workaround will not prevent attacks from authenticated users. Use this workaround only if you cannot disable the Printer Spooler service.
Warning Using Registry Editor incorrectly can cause serious problems that may require that you reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to modify the registry, view the "Change Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.
Note We recommend backing up the registry before you modify it
- Click Start, click Run, type regedt32 and then click OK.
- In Registry Editor, locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\NullSessionPipes - Edit the registry key and remove the SPOOLSS value.
- Restart the affected system after performing these actions.
Impact of workaround. Anonymous connections to the Print Spooler service will not be allowed. This is the default behavior of later operating system versions.

FAQ for Buffer Overflow in Print Spooler Vulnerability - CVE-2009-0228
What is the scope of the vulnerability?
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts.
What causes the vulnerability?
The Windows Print Spooler contains a buffer overflow due to the improper parsing of certain printing data structures.
What is the Print Spooler service?
The Print Spooler service is an executable file that is installed as a service. The spooler is loaded when the operating system starts, and it continues to run until the operating system is shut down. The Print Spooler service manages the printing process, which includes such tasks as retrieving the location of the correct printer driver, loading that driver, spooling high-level function calls into a print job, and scheduling print jobs. When the tasks for a particular print job are complete, the Print Spooler service passes the job to the print router. For more information, see the TechNet article, How Network Printing Works.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could run arbitrary code on a user's system with system privileges. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts.
How could an attacker exploit the vulnerability?
For remote code execution to occur, an attacker would first need to set up a malicious print server that can be accessed by an affected system. The attacker could then send a specially crafted RPC request to the affected system that would cause the affected system to improperly parse the ShareName on the attacker's print server during enumeration. This would allow the attacker to perform remote code execution on the affected system with system-level privileges.
What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What is the scope of the vulnerability?
This is an information disclosure vulnerability. An attacker who successfully exploited this vulnerability could read or print any file on the system. This action could be taken even if the user does not have administrative access.
What causes the vulnerability?
The Windows Printing Service does not properly check the files that can be included with separator pages.
What is the Print Spooler service?
The Print Spooler service is an executable file that is installed as a service. The spooler is loaded when the operating system starts, and it continues to run until the operating system is shut down. The Print Spooler service manages the printing process, which includes such tasks as retrieving the location of the correct printer driver, loading that driver, spooling high-level function calls into a print job, and scheduling print jobs. When the tasks for a particular print job are complete, the Print Spooler service passes the job to the print router. For more information, see the TechNet article, How Network Printing Works.
What is a separator page?
A separator or banner page typically states who sent the document to the printer and gives the date and time of printing. You can use one of the standard separator pages or create a custom page. Windows provides three separator page files, which are located in the %systemroot%\System32 folder. For more information, see the TechNet article, Using separator pages.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could read or print any file on an affected system. The attacker would not have the ability to change the contents of a file.
How could an attacker exploit the vulnerability?
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then create a specially crafted separator page that included any file from the system that the attacker wanted to include in the print request.
On all versions of Microsoft Windows, the attacker needs the "Manage Printer" privilege to exploit this issue. On Windows Vista and Windows Server 2008, the local user is automatically given this permission if they install a local printer. This can be accomplished without administrative privileges if the printer driver is included by default.

FAQ for Print Spooler Load Library Vulnerability - CVE-2009-0230
What is the scope of the vulnerability?
This is an elevation of privilege vulnerability. An attacker who successfully exploited this vulnerability could execute arbitrary code and take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
What causes the vulnerability?
The Windows Print Spooler does not properly validate the paths from which a DLL may be loaded.
What is the Print Spooler service?
The Print Spooler service is an executable file that is installed as a service. The spooler is loaded when the operating system starts, and it continues to run until the operating system is shut down. The Print Spooler service manages the printing process, which includes such tasks as retrieving the location of the correct printer driver, loading that driver, spooling high-level function calls into a print job, and scheduling print jobs. When the tasks for a particular print job are complete, the Print Spooler service passes the job to the print router. For more information, see the TechNet article, How Network Printing Works.
What is a DLL?
A dynamic-link library (DLL) is a module that contains functions and data that can be used by another module (application or DLL). A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined. Although a DLL can export data, its data is generally used only by its functions. However, there is nothing to prevent another module from reading or writing that address. DLLs provide a way to modularize applications so that their functionality can be updated and reused more easily. DLLs also help reduce memory overhead when several applications use the same functionality at the same time, because although each application receives its own copy of the DLL data, the applications share the DLL code. For more information, see the MSDN article, Dynamic-Link Libraries.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could run arbitrary code with the same rights as the Windows Print Spooler. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
How could an attacker exploit the vulnerability?
To exploit this vulnerability, an attacker would have to store a malicious DLL in a location that is accessible by the print spooler. The attacker would then create a specially crafted RPC message and send the message to an affected system. The message would cause the print spooler to load the malicious DLL and execute code with elevated privileges.
On all versions of Microsoft Windows, the attacker needs the "Manage Printer" privilege to exploit this issue. On Windows Vista and Windows Server 2008, the local user is automatically given this permission when installing a local printer. This can be accomplished without administrative privileges if the printer driver is included by default.
What systems are primarily at risk from the vulnerability?
Systems configured as print servers are primarily at risk from this vulnerability.
What does the update do?
The update addresses this vulnerability by restricting the paths from which the print spooler can load a DLL.
When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.
When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.

Update Compatibility Evaluator and Application Compatibility Toolkit
Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit 5.0.
The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.

Installing the Update
When you install this security update, the installer checks whether one or more of the files that are being updated on your system have previously been updated by a Microsoft hotfix.
If you have previously installed a hotfix to update one of these files, the installer copies the RTMQFE, SP1QFE, or SP2QFE files to your system. Otherwise, the installer copies the RTMGDR, SP1GDR, or SP2GDR files to your system. Security updates may not contain all variations of these files. For more information about this behavior, see Microsoft Knowledge Base Article 824994.
For more information about the installer, visit the Microsoft TechNet Web site.
For more information about the terminology that appears in this bulletin, such as hotfix, see Microsoft Knowledge Base Article 824684.
This security update supports the following setup switches.
| Switch | Description |
|---|---|
| /help | Displays the command-line options. |
| Setup Modes | |
| /passive | Unattended Setup mode. No user interaction is required, but installation status is displayed. If a restart is required at the end of Setup, a dialog box will be presented to the user with a timer warning that the computer will restart in 30 seconds. |
| /quiet | Quiet mode. This is the same as unattended mode, but no status or error messages are displayed. |
| Restart Options | |
| /norestart | Does not restart when installation has completed. |
| /forcerestart | Restarts the computer after installation and force other applications to close at shutdown without saving open files first. |
| /warnrestart[:x] | Presents a dialog box with a timer warning the user that the computer will restart in x seconds. (The default setting is 30 seconds.) Intended for use with the /quiet switch or the /passive switch. |
| /promptrestart | Displays a dialog box prompting the local user to allow a restart. |
| Special Options | |
| /overwriteoem | Overwrites OEM files without prompting. |
| /nobackup | Does not back up files needed for uninstall. |
| /forceappsclose | Forces other programs to close when the computer shuts down. |
| /log:path | Allows the redirection of installation log files. |
| /extract[:path] | Extracts files without starting the Setup program. |
| /ER | Enables extended error reporting. |
| /verbose | Enables verbose logging. During installation, creates %Windir%\CabBuild.log. This log details the files that are copied. Using this switch may cause the installation to proceed more slowly. |
Note You can combine these switches into one command. For backward compatibility, the security update also supports the setup switches that the earlier version of the Setup program uses. For more information about the supported installation switches, see Microsoft Knowledge Base Article 262841.

File Version Verification
Because there are several editions of Microsoft Windows, the following steps may be different on your system. If they are, see your product documentation to complete these steps.
- Click Start, and then click Search.
- In the Search Results pane, click All files and folders under Search Companion.
- In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
- In the list of files, right-click a file name from the appropriate file information table, and then click Properties. Note Depending on the edition of the operating system, or the programs that are installed on your system, some of the files that are listed in the file information table may not be installed.
- On the Version tab, determine the version of the file that is installed on your system by comparing it to the version that is documented in the appropriate file information table. Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation.
Registry Key Verification
You may also be able to verify the files that this security update has installed by reviewing the registry keys listed in the Reference Table in this section.
