DNS Spoofing Attack Vulnerability - CVE-2008-0087
A spoofing vulnerability exists in Windows DNS clients. The vulnerability could allow an unauthenticated attacker to send malicious responses to DNS requests made by vulnerable clients, thereby spoofing or redirecting Internet traffic from legitimate locations.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2008-0087.
Mitigating Factors for DNS Spoofing Attack Vulnerability - CVE-2008-0087
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.
- Microsoft has not identified any mitigations for this vulnerability.
Workarounds for DNS Spoofing Attack Vulnerability - CVE-2008-0087
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.

FAQ for DNS Spoofing Attack Vulnerability - CVE-2008-0087
What is the scope of the vulnerability?
A spoofing vulnerability exists in Windows DNS Clients. An attacker who successfully exploited this vulnerability could impersonate a legitimate address.
What causes the vulnerability?
The Windows DNS Client service doesn’t provide enough entropy in its random choice of transaction values when performing DNS queries.
What might an attacker use the vulnerability to do?
An attacker who has successfully gained information about DNS client transaction IDs could use that information to send malicious responses to DNS requests.
How could an attacker exploit the vulnerability?
An attacker who successfully exploited this vulnerability could respond to a DNS query with false or misleading information, thereby redirecting Internet traffic from legitimate locations to an address of the attacker’s choice.
What is the Domain Name System (DNS)?
Domain Name System (DNS) is one of the industry-standard suite of protocols that comprise TCP/IP. DNS is implemented using two software components: the DNS server and the DNS client (or resolver). Both components are run as background service applications. Network resources are identified by numeric IP addresses, but these IP addresses are difficult for network users to remember. The DNS database contains records that map user-friendly alphanumeric names for network resources to the IP address used by those resources for communication. In this way, DNS acts as a mnemonic device, making network resources easier to remember for network users. For more information and to view logical diagrams illustrating how DNS fits with other Windows technologies, review the article How DNS Works.
Could the vulnerability be exploited over the Internet?
Yes, an attacker could exploit this vulnerability over the Internet by sending specific responses to an Internet-facing client system that is performing DNS queries.
What systems are primarily at risk from the vulnerability?
Any Windows system that is connected to a network or the Internet would be at risk. Windows Vista SP1 and Windows Server 2008 are not affected by this vulnerability.
What does the update do?
The update removes this vulnerability by increasing the randomness of the transaction IDs in DNS client communications.
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.

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 versions of Microsoft Windows, the following steps may be different on your computer. 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 version of the operating system or programs installed, 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 computer 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.

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.

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 versions of Microsoft Windows, the following steps may be different on your computer. 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 version of the operating system or programs installed, 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 computer 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.
