Microsoft Security Bulletin MS12-032 - Important
Vulnerability in TCP/IP Could Allow Elevation of Privilege (2688338)
Published: May 08, 2012 | Updated: May 09, 2012
Version: 1.1
General Information
Executive Summary
This security update resolves one publicly disclosed and one privately reported vulnerability in Microsoft Windows. The more severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to a system and runs a specially crafted application.
This security update is rated Important for all supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by modifying the way that Windows Firewall handles outbound broadcast packets and by modifying the way that the Windows TCP/IP stack handles the binding of an IPv6 address to a local interface. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Recommendation. The majority of 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.

Microsoft has not identified any workarounds for this vulnerability.
FAQ for Windows Firewall Bypass Vulnerability - CVE-2012-0174
What is the scope of the vulnerability?
This is a security feature bypass vulnerability. An attacker who successfully exploited this vulnerability could bypass Windows Firewall to facilitate the exploitation of other vulnerabilities.
What causes the vulnerability?
The vulnerability is caused when Windows Firewall fails to properly filter outbound broadcast packets with an outbound firewall rule applied.
What is the component affected by this vulnerability?
The component affected by this vulnerability is the TCP/IP stack (tcpip.sys).
What is TCP/IP?
TCP/IP is a set of networking protocols that are widely used on the Internet. TCP/IP provides communications across interconnected networks of computers that have diverse hardware architectures and that run various operating systems. TCP/IP includes standards for how computers communicate and conventions for connecting networks and for routing traffic. For more information about TCP/IP, see the TechNet article, Overview of networking and TCP/IP.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could bypass Windows Firewall. An attacker could then use another vulnerability to acquire information about the target system or execute code on the target system.
How could an attacker exploit the vulnerability?
In order to use this vulnerability, an attacker would first have to gain access to the local subnet of the target computer. An attacker could then use another vulnerability to acquire information about the target system or execute code on the target system.
What systems are primarily at risk from the vulnerability?
Workstations and servers are primarily at risk from this vulnerability.
What does the update do?
The update addresses the vulnerability by modifying the way that Windows Firewall handles outbound broadcast packets.
What is the default outbound firewall policy?
The default outbound firewall policy is configured to allow all outbound network traffic from the host. In order to block unwanted outbound network traffic, customers will need to create firewall rules to block traffic. For more information about adding outbound firewall rules, please see the TechNet article Creating Rules that Block Unwanted Outbound Network Traffic.
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.
TCP/IP Double Free Vulnerability - CVE-2012-0179
An elevation of privilege vulnerability exists in the Windows TCP/IP stack that affects Windows 7 and Windows Server 2008 R2. All editions of Microsoft Windows XP, Windows Server 2003, Windows Vista, and Window Server 2008 are not affected. This vulnerability is caused when the Windows TCP/IP stack fails to properly handle the binding of IPv6 addresses.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0179.
Mitigating Factors for TCP/IP Double Free Vulnerability - CVE-2012-0179
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 must have valid logon credentials and be able to log on locally to exploit this vulnerability.
Workarounds for TCP/IP Double Free Vulnerability - CVE-2012-0179
Microsoft has not identified any workarounds for this vulnerability.
FAQ for TCP/IP Double Free Vulnerability - CVE-2012-0179

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 enter an update file name in the Search box.
- When the file appears under Programs, right-click the file name and click Properties.
- On the General tab, compare the file size with the file information tables provided in the bulletin KB article.
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. - You can also click the Details tab and compare information, such as file version and date modified, with the file information tables provided in the bulletin KB article.
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. - Finally, you can also click the Previous Versions tab and compare file information for the previous version of the file with the file information for the new, or updated, version of the file.
