Microsoft Security Bulletin MS13-032 - Important
Vulnerability in Active Directory Could Lead to Denial of Service (2830914)
Published: April 09, 2013
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Active Directory. The vulnerability could allow denial of service if an attacker sends a specially crafted query to the Lightweight Directory Access Protocol (LDAP) service.
This security update is rated Important for Active Directory, Active Directory Application Mode (ADAM), Active Directory Lightweight Directory Service (AD LDS), and Active Directory Services on Microsoft Windows servers (excluding Itanium-based systems) and rated Low on Microsoft Windows clients.
The security update addresses the vulnerability by correcting how the LDAP service handles specially crafted LDAP queries. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Recommendation. Most customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.
For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service.

Memory Consumption Vulnerability - CVE-2013-1282
A denial of service vulnerability exists in implementations of Active Directory that could cause the service to stop responding. The vulnerability is caused when the LDAP service fails to handle a specially crafted query.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2013-1282.
Mitigating Factors
An attacker must have valid logon credentials to exploit this vulnerability. The vulnerability could not be exploited remotely by anonymous users. However, the affected component is available remotely to users who have standard user accounts. In certain configurations, anonymous users could authenticate as the Guest account.
Workarounds
Microsoft has not identified any workarounds for this vulnerability.
FAQ
What is the scope of the vulnerability?
This is a denial of service vulnerability.
What causes the vulnerability?
The vulnerability is caused when the LDAP service fails to properly handle a specially crafted LDAP query.
What is Active Directory?
Active Directory is a Windows component that provides central authentication and authorization services for Windows-based systems.
What is Active Directory Services?
Active Directory Services contains an extensible and scalable set of services that enables you to efficiently manage corporate identities, credentials, information protection, and system and application settings. Active Directory Services include Active Directory Certificate Services (AD CS), Active Directory Domain Services (AD DS), Active Directory Federation Services (AD FS), Active Directory Lightweight Directory Services (AD LDS), and Active Directory Rights Management Services (AD RMS).
What is Active Directory Lightweight Directory Service (AD LDS)?
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 for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. AD LDS replaces Active Directory Application Mode (ADAM), which is available for Windows XP and Windows Server 2003. For more information on AD LDS, see the TechNet article, Active Directory Lightweight Directory Services.
What is Active Directory Application Mode?
Active Directory Application Mode (ADAM) is a Lightweight Directory Access Protocol (LDAP) directory service that runs as a user service for Windows XP and Windows Server 2003, rather than as a system service. For more information on ADAM, please see the TechNet article, Introducing ADAM.
What is the Lightweight Directory Access Protocol (LDAP)?
The Lightweight Directory Access Protocol (LDAP) is a directory service protocol that runs directly over the TCP/IP stack. The information model (for both data and namespaces) of LDAP is similar to that of the X.500 OSI directory service, but with fewer features and lower resource requirements than X.500. Unlike most other Internet protocols, LDAP has an associated API that simplifies writing Internet directory service applications. The LDAP API is applicable to directory management and browser applications that do not have directory service support as their primary function. LDAP cannot create directories or specify how a directory service operates.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could cause the LDAP service to become non-responsive.
How could an attacker exploit the vulnerability?
An attacker could exploit this vulnerability by sending a specially crafted query to the LDAP service.
What systems are primarily at risk from the vulnerability?
Servers are primarily at risk from this vulnerability.
What does the update do?
The update addresses the vulnerability by correcting how the LDAP service handles specially crafted LDAP queries.
When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through coordinated vulnerability 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.
Update Information
Detection and Deployment Tools and Guidance
Several resources are available to help administrators deploy security updates.
- Microsoft Baseline Security Analyzer (MBSA) lets administrators scan local and remote systems for missing security updates and common security misconfigurations.
- Windows Server Update Services (WSUS), Systems Management Server (SMS), and System Center Configuration Manager (SCCM) help administrators distribute security updates.
- The Update Compatibility Evaluator components included with Application Compatibility Toolkit aid in streamlining the testing and validation of Windows updates against installed applications.
