A denial of service vulnerability exists in implementations of Active Directory on Microsoft Windows 2000 Server, Windows Server 2003, and Windows Server 2008. The vulnerability also exists in implementations of Active Directory Application Mode (ADAM) when installed on Windows XP and Windows Server 2003, and Active Directory Lightweight Directory Service (AD LDS) on Windows Server 2008. The vulnerability is due to stack space exhaustion during execution of certain types of LDAP or LDAPS requests. An attacker who successfully exploited this vulnerability could cause the affected system to stop responding.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2009-1928.

Mitigating Factors for LSASS Recursive Stack Overflow Vulnerability - CVE-2009-1928

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 LSASS Recursive Stack Overflow Vulnerability - CVE-2009-1928

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 389, 636, 3268 and 3269 at the firewall

    Block the following at the firewall:

    TCP ports 389, 636, 3268 and 3269

    These ports are used to initiate a connection with the affected component. Blocking them at the enterprise firewall, both inbound and outbound, will help prevent systems that are behind that firewall from attempts to exploit this vulnerability. Ports 389 and 636 provide LDAP and secure LDAP services respectively, while ports 3268 and 3269 are used by the Global Catalog server which also processes LDAP requests. Active Directory Application Mode (ADAM) and Active Directory Lightweight Directory Service (AD LDS) allow administrators to configure LDAP ports which are non-default. When applying this workaround, those ports should be blocked at the firewall as well in order to prevent exploitation.

    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. For more information about the Windows Firewall, see How to Configure Windows Firewall on a Single Computer.

FAQ for LSASS Recursive Stack Overflow Vulnerability - CVE-2009-1928

What is the scope of the vulnerability? 
This is a denial of service vulnerability. An attacker who exploited this vulnerability could cause the affected system to stop responding and require it to be restarted. Note that the denial of service vulnerability would not allow an attacker to execute code or to elevate their user rights, but it could cause the affected system to stop accepting requests.

What causes the vulnerability? 
The LDAP service improperly processes specific LDAP or LDAPS requests in a manner that can lead to stack space exhaustion.

What is Active Directory? 
The main purpose of Active Directory is to provide central authentication and authorization services for Windows-based computers.

What is Active Directory Lightweight Directory Service? 
Active Directory Lightweight Directory Services (AD LDS) is an independent mode of Active Directory that provides dedicated directory services for applications. AD LDS is available in Windows Server 2008 and later, and replaces Active Directory Application Mode (ADAM), which was available in Windows XP and Windows Server 2003.

What is LDAP? 
Lightweight Directory Access Protocol (LDAP) is an open network protocol standard designed to provide access to distributed directories.

What is LDAP over SSL (LDAPS)? 
By default, LDAP traffic is transmitted unsecured. However, it is possible to make LDAP traffic confidential and secure from modification by using Secure Sockets Layer (SSL)/Transport Layer Security (TLS) technology. Administrators can enable LDAP over SSL (LDAPS) by installing a properly formatted digital certificate from either a Microsoft certification authority (CA) or a non-Microsoft CA, according to the guidelines in Microsoft Knowledge Base Article 321051.

Is LDAP over SSL available by default? 
No. Before an LDAP server can participate in an SSL session, the administrator must have obtained a digital certificate and installed it on the server. Unless this has been done, LDAP over SSL is not available.

How can I confirm whether my server is running the LDAP service if I am using Active Directory
To confirm whether a server is listening to LDAP or LDAPS queries, run the following command from an administrator command prompt and look to see if the system is listening on the LDAP port (389) or the LDAPS port (636), or either of the Global Catalog service ports (3268 or 3269):

netstat –a

LDAP is enabled if the results contain any of the following:

Proto Local Address Foreign Address State
TCP 0.0.0.0:389 0.0.0.0:0 LISTENING
TCP 0.0.0.0:636 0.0.0.0:0 LISTENING
TCP 0.0.0.0:3268 0.0.0.0:0 LISTENING
TCP 0.0.0.0:3269 0.0.0.0:0 LISTENING

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could cause a user’s system to stop responding and require a restart.

How could an attacker exploit the vulnerability? 
An attacker could try to exploit the vulnerability by sending a specially crafted LDAP or LDAPS packet to the ADAM, AD LDS, or Active Directory server. For Microsoft Windows 2000 Server, an anonymous user with access to the target network could deliver a specially crafted network packet to the affected system in order to exploit this vulnerability. On all other affected platforms, the attacker must have valid authentication credentials in order to exploit this vulnerability.

What systems are primarily at risk from the vulnerability? 
Lightweight Directory Access Protocol (LDAP) is a requirement for Active Directory, ADAM, and AD LDS. Therefore, any system running as an ADAM, AD LDS, or Active Directory server is affected by this vulnerability.

What does the update do? 
The update addresses the vulnerability by correctly processing malformed LDAP or LDAPS requests.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through responsible disclosure.

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 when this security bulletin was originally issued.

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.

    1. Click Start, and then click Search.
    2. In the Search Results pane, click All files and folders under Search Companion.
    3. In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
    4. 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.
    5. 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.

    These registry keys may not contain a complete list of installed files. Also, these registry keys may not be created correctly when an administrator or an OEM integrates or slipstreams this security update into the Windows installation source files.

Deployment Information

Installing the Update

When you install this security update, the installer checks to see if 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.

/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

/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 many of 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.
