Vulnerabilities in Ancillary Function Driver Could Allow Elevation of Privilege (2645640)
Published: February 14, 2012
Version: 1.0
General Information
Executive Summary
This security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker logs on to a user's system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit the vulnerabilities.
This security update is rated Important for all supported editions of Windows XP (except x86-based), Windows Server 2003, Windows Vista (except x86-based), Windows Server 2008 (except x86-based), Windows 7 (except x86-based), 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 correcting the way that the AFD validates input before passing the input from user-mode to the Windows kernel. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Frequently Asked Questions (FAQ) Related to This Security Update
Where are the file information details?
Refer to the reference tables in the Security Update Deployment section for the location of the file information details.
Why does this update address several reported security vulnerabilities?
This update contains support for several vulnerabilities because the modifications that are required to address these issues are located in related files. Instead of having to install several updates that are almost the same, customers need to install this update only.
Why is Windows Server 2003 Service Pack 2 the only affected 32-bit edition of Windows in this bulletin? This security update addresses two vulnerabilities, CVE-2012-0148 and CVE-2012-0149. The former does not affect any 32-bit editions of Windows, while the latter only affects supported editions of Windows Server 2003, including the 32-bit editions. Therefore, Windows Server 2003 Service Pack 2 is the only 32-bit edition of Windows included as affected software in this bulletin.

FAQ for AfdPoll Elevation of Privilege Vulnerability - CVE-2012-0148
What is the scope of the vulnerability?
This is an elevation of privilege vulnerability. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode and take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
What causes the vulnerability?
The vulnerability is caused when the afd.sys driver improperly validates input when receiving data from user mode.
What is the Ancillary Function Driver (AFD)?
The AFD component provides the "ancillary function driver," which supports Windows sockets applications and is contained in the afd.sys file. The afd.sys driver runs in kernel mode and manages the Winsock TCP/IP communications protocol. This Winsock Kernel Interface provides access to the TDI transports.
What is the Transport Driver Interface (TDI)?
The Transport Driver Interface (TDI) defines a kernel-mode network interface that is exposed at the upper edge of all transport protocol stacks. The highest level protocol driver in every such stack supports the TDI interface for still higher level kernel-mode network clients. For more information about the TDI Component, see the MSDN article, Transport Driver Interface.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode and take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
How could an attacker exploit the vulnerability?
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take complete control over the affected system.
What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.
What does the update do?
The update addresses the vulnerability by correcting the way that the AFD validates input before passing the input from user-mode to the Windows kernel.
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.
