DirectShow Insecure Library Loading Vulnerability - CVE-2011-0032
A remote code execution vulnerability exists in the way that Microsoft DirectShow handles the loading of DLL files. 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 with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-0032.
Mitigating Factors for DirectShow Insecure Library Loading Vulnerability - CVE-2011-0032
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:
- For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open a media file (such as .wtv, .drv-ms, or .mpg files).
- The file sharing protocol, Server Message Block (SMB), is often disabled on the perimeter firewall. This limits the potential attack vectors for this vulnerability.
- An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Workarounds for DirectShow Insecure Library Loading Vulnerability - CVE-2011-0032
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:
- Disable loading of libraries from WebDAV and remote network shares
Note See Microsoft Knowledge Base Article 2264107 to deploy a workaround tool that allows customers to disable the loading of libraries from remote network or WebDAV shares. This tool can be configured to disallow insecure loading on a per-application or a global system basis.
Customers who are informed by their vendor of an application being vulnerable can use this tool to help protect against attempts to exploit this issue.
Note See Microsoft Knowledge Base Article 2264107 to use the automated Microsoft Fix it solution to deploy the registry key to block the loading of libraries for SMB and WebDAV shares. Note that this Fix it solution does require you to install the workaround tool also described in Microsoft Knowledge Base Article 2264107 first. This Fix it solution only deploys the registry key and requires the workaround tool in order to be effective. We recommend that administrators review the KB article closely prior to deploying this Fix it solution.
- Disable the WebClient service
Disabling the WebClient service helps protect affected systems from attempts to exploit this vulnerability by blocking the most likely remote attack vector through the Web Distributed Authoring and Versioning (WebDAV) client service. After applying this workaround it is still possible for remote attackers who successfully exploit this vulnerability to cause the system to run programs located on the targeted user's computer or the Local Area Network (LAN), but users will be prompted for confirmation before opening arbitrary programs from the Internet.
To disable the WebClient Service, follow these steps:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Disabled. If the service is running, click Stop.
- Click OK and exit the management application.
Impact of workaround. When the WebClient service is disabled, Web Distributed Authoring and Versioning (WebDAV) requests are not transmitted. In addition, any services that explicitly depend on the Web Client service will not start, and an error message will be logged in the System log. For example, WebDAV shares will be inaccessible from the client computer.
How to undo the workaround.
To re-enable the WebClient Service, follow these steps:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Automatic. If the service is not running, click Start.
- Click OK and exit the management application.
- 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 the TechNet article, 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
How to undo the workaround. Unblock TCP ports 139 and 445 at the firewall. For more information about ports, see TCP and UDP Port Assignments.
FAQ for DirectShow Insecure Library Loading Vulnerability - CVE-2011-0032
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 with full user rights.
What causes the vulnerability?
The vulnerability is caused when Microsoft DirectShow incorrectly restricts the path used for loading external libraries.
What is DirectShow?
DirectShow is a DirectX low-level Application Programming Interface (API) used by Windows programs for multimedia support. Within DirectX, the DirectShow technology performs client-side audio and video sourcing, manipulation and rendering.
Microsoft DirectShow is used for streaming media on Microsoft Windows operating systems. DirectShow is used for high-quality capture and playback of multimedia streams. It automatically detects and uses video and audio acceleration hardware when available, but also supports systems without acceleration hardware. DirectShow is also integrated with other DirectX technologies. Some examples of applications that use DirectShow include DVD players, video editing applications, AVI to ASF converters, MP3 players, and digital video capture applications.
What is DirectX?
Microsoft DirectX is a feature of the Windows operating system. It is used for streaming media on Microsoft Windows operating systems to enable graphics and sound when playing games or watching video.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If a user is logged-on with administrative user rights, an attacker could take complete control of the affected system. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
How could an attacker exploit the vulnerability?
An attacker could convince a user to open a legitimate Windows Media Player file (such as a .wtv, .drv-ms, or .mpg file) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. Then, while opening the media file, Microsoft DirectShow could attempt to load the DLL file and execute any code it contained.
In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a legitimate media file attachment (such as a .wtv, .drv-ms, or .mpg file) to a user, and convincing the user to place the attachment into a directory containing a specially crafted DLL file and to open the media file. Then, while opening the media file, Microsoft DirectShow could attempt to load the DLL file and execute any code it contained.
In a network attack scenario, an attacker could place a legitimate media file and a specially crafted DLL in a network share, UNC, or WebDAV location and then convince the user to open the media file.
What is a Windows Recorded TV Show (.wtv) file?
The Windows Recorded TV Show (WTV) file format replaces the previously used DVR-MS file format. Video is encoded using the MPEG-2 standard and audio using MPEG-1 Layer II or Dolby Digital AC-3 (ATSC A/52) standards. The format extends these standards by including metadata about the content and digital rights management. Access to WTV file content is made using the Stream Buffer Engine DirectShow source filter. Unlike .dvr-ms files, which are produced by previous versions of Media Center and are based on the ASF file format, WTV files are based on a new file format.
What is a Microsoft Digital Video Recording (.dvr-ms) file?
Microsoft Digital Video Recording files are files created by the Stream Buffer Engine (SBE) that are stored with the .dvr-ms file extension. When the SBE is being controlled from the Video Control, the audio and video elementary streams are examined for copy protection/control information. If this information does not specify that the content should be encrypted, then an unencrypted file will be created that can later be accessed by any DirectShow-based application that uses the SBE. If the information specifies that the content should be encrypted, then the resulting file will not be accessible, except for playback only on the same machine that was used to make the recording. DirectShow applications that are not based on the Video Control can use the SBE directly to create and play back unencrypted dvr-ms files.
What are DirectShow filters?
DirectShow provides a set of default filters that install automatically with Microsoft Windows. These filters support many data formats while providing a high degree of hardware independence. An application can also register and install custom filters on the target system. For a full list of filters and further information, see the MSDN article, DirectShow Filters.
What systems are primarily at risk from the vulnerability?
This vulnerability mainly affects workstations where users may be expected to open attachments from untrusted network locations. Servers could also be at risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.
What does the update do?
The update addresses this vulnerability by correcting the manner in which Microsoft DirectShow loads external libraries.
Is this vulnerability related to Microsoft Security Advisory 2269637?
Yes, this vulnerability is related to the class of vulnerabilities, described in Microsoft Security Advisory 2269637, that affects how applications load external libraries. This security update addresses a particular instance of this type of vulnerability.
When this security bulletin was issued, had this vulnerability been publicly disclosed?
Yes. This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CVE-2011-0032.
When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had seen examples of proof of concept code published publicly but had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.
DVR-MS Vulnerability - CVE-2011-0042
A remote code execution vulnerability exists in the way that Windows Media Player and Windows Media Center handle .dvr-ms files. This vulnerability could allow an attacker to execute arbitrary code if the attacker convinces a user to open a specially crafted .dvr-ms file. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-0042.
Mitigating Factors for DVR-MS Vulnerability - CVE-2011-0042
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:
- An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
- The vulnerability cannot be exploited automatically through e-mail. For an attack to be successful a user would have to open a specially crafted .dvr-ms file that was sent as an attachment in an e-mail message. An attacker has no way to force a user to open a specially crafted .dvr-ms file. For an attack to be successful an attacker would have to convince a user to open the file.
- In a Web-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.
Workarounds for DVR-MS Vulnerability - CVE-2011-0042
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:
- Restrict access to the Stream Buffer Engine (SBE.dll)
Run the following commands from a command prompt as an administrator:
takeown /f "%windir%\system32\sbe.dll"
cacls "%windir%\system32\sbe.dll" /E /P everyone:NImpact of workaround. Play back of .dvr-ms files generated by the Stream Buffer Engine is disabled.

Deployment Information
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, see Microsoft Knowledge Base Article 832475.
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. |
| /integrate:path | Integrates the update into the Windows source files. These files are located at the path that is specified in the switch. |
| /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.

Verifying That the Update Has Been Applied
- Microsoft Baseline Security Analyzer
To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information.
- 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.
