  • To help protect from network-based attempts to exploit this vulnerability, use a personal firewall, such as the Internet Connection Firewall

    All supported editions of Windows Vista come with Windows Firewall, a two-way firewall that is automatically enabled.

    For all supported editions of Windows Server 2003, use the Internet Connection Firewall feature to help protect your Internet connection by blocking unsolicited incoming traffic. Microsoft recommends that you block all unsolicited incoming communication from the Internet.

    To enable the Windows Firewall feature by using the Network Setup Wizard, perform the following steps:

    1. Click Start, and then click Control Panel.
    2. Double-click Network Connections and then click Change Windows Firewall Settings.
    3. On the General tab, ensure that the On (recommended) value is selected. This will enable the Windows Firewall.
    4. When the Windows Firewall is enabled, select Don’t allow exceptions to prohibit all incoming traffic.

    For Windows Server 2003 systems, configure Internet Connection Firewall manually for a connection using the following steps:

    1. Click Start, and then click Control Panel.
    2. In the default Category View, click Networking and Internet Connections, and then click Network Connections.
    3. Right-click the connection on which you want to enable Internet Connection Firewall, and then click Properties.
    4. Click the Advanced tab.
    5. Click to select the Protect my computer or network by limiting or preventing access to this computer from the Internet check box, and then click OK.

FAQ for Local Security Authority Subsystem Service Integer Overflow Vulnerability - CVE-2009-2524

What is the scope of the vulnerability? 
This is a denial of service vulnerability. A specially crafted authentication frame may allow an unauthenticated attacker to cause the server-side LSASS process to stop responding and restart the computer.

What causes the vulnerability? 
The vulnerability is present because the Windows NTLM implementation in LSASS does not properly handle specific malformed packets during the authentication process. A specific malformed packet may result in an integer underflow in the LSASS process.

What is LSASS? 
The Local Security Authority Subsystem Service (LSASS) provides an interface for managing local security, domain authentication, and Active Directory service processes. It handles authentication for the client and for the server. The LSASS also contains features that are used to support Active Directory utilities.

What is NTLM? 
Windows Challenge/Response (NT Lan Manager or NTLM) is the authentication protocol used on networks that include systems running the Windows operating system and on stand-alone systems. NTLM credentials are based on data obtained during the interactive logon process and consist of a domain name, a user name, and a one-way hash of the user's password. NTLM uses an encrypted challenge/response protocol to authenticate a user without sending the user's password over the network. Instead, the system requesting authentication must perform a calculation that proves it has access to the secured NTLM credentials.

Interactive NTLM authentication over a network typically involves two systems: a client system, where the user is requesting authentication, and a domain controller, where information related to the user's password is kept. Non-interactive authentication, which may be required to permit an already logged-on user to access a resource such as a server application, typically involves three systems: a client, a server, and a domain controller that does the authentication calculations on behalf of the server.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could cause an affected system to automatically reboot.

How could an attacker exploit the vulnerability? 
An attacker could exploit this vulnerability by sending a maliciously crafted packet during the NTLM authentication process.

What systems are primarily at risk from the vulnerability? 
Servers that allow clients to authenticate using NTLM are at risk.

What does the update do? 
The update ensures that LSASS handles specific values used in the authentication process correctly.

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 and had not seen any examples of proof of concept code published when this security bulletin was originally issued.

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.

Supported Security Update Installation Switches
SwitchDescription
/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 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.

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.
