[1]Windows Live Mail is an out-of-box component on this operating system that needs to be installed separately for the vulnerability to exist.

Why is this vulnerability considered Important on Windows 7 and Windows Server 2008 R2? 
On Windows 7 and Windows Server 2008 R2, Windows Live Mail is an out-of-box component which is not installed by default. A user would have to install the application separately in order to be affected by this issue. However, the vulnerable code is present on the machine in a default installation in the file inetcomm.dll, and installing this update will remedy the vulnerability whether or not the attack vector exists.

I am running Windows 7 or Windows Server 2008 R2 without Windows Live Mail installed. Why am I still being offered this security update? 
This vulnerability is present in inetcomm.dll, which is a core component of the operating system. However, the only attack vector is through the use of Windows Live Mail. You are still being offered this security update as a defense-in-depth update and to fully address the vulnerability on the system.

An unauthenticated remote code execution vulnerability exists in the way that Windows Mail Client handles specially crafted mail responses. An attempt to exploit the vulnerability would not require authentication, allowing an attacker to exploit the vulnerability by sending a specially crafted response to a client initiating a connection to a server under his control using the common mail protocols POP3 and IMAP.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-0816.

Mitigating Factors for Outlook Express and Windows Mail Integer Overflow Vulnerability - CVE-2010-0816

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 who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  • An attacker cannot send a malicious e-mail to trigger this vulnerability.
  • Customers using SSL encryption on top of POP3 or IMAP protocols are no longer vulnerable to man-in-the-middle attacks exploiting this vulnerability, and would only be affected if the client can be enticed to connect to a malicious or compromised e-mail server.

Workarounds for Outlook Express and Windows Mail Integer Overflow Vulnerability - CVE-2010-0816

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. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

  • Use web-based e-mail when possible

    If available, use web-based e-mail instead of IMAP or POP3 to check e-mail.

FAQ for Outlook Express and Windows Mail Integer Overflow Vulnerability - CVE-2010-0816

What is the scope of the vulnerability? 
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

What causes the vulnerability? 
The vulnerability is caused when a common library used by Outlook Express and Windows Mail insufficiently validates network data before using that data to calculate the necessary size of a buffer.

What is Windows Mail? 
Windows Mail (formerly Outlook Express) is an online communication tool for use with Windows.

What are the POP3 and IMAP mail protocols? 
The Post Office Protocol 3 (POP3) servers hold incoming e-mail messages until you check your e-mail, at which point they're transferred to your computer. POP3 is the most common account type for personal e-mail. Messages are typically deleted from the server when you check your e-mail. Internet Message Access Protocol 4 (IMAP4) is a protocol for reading mail and accessing public folders on remote servers. Clients can log on to a mail server and use IMAP4 to download message headers and then read messages individually while online.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

How could an attacker exploit the vulnerability? 
An attacker could exploit this vulnerability by setting up a malicious e-mail server and convincing the client to connect to this machine. He would then respond with a crafted POP3 or IMAP response, causing the client to trigger the vulnerability. Alternatively, a man-in-the-middle could edit specific server responses and cause this vulnerability to be triggered.

What systems are primarily at risk from the vulnerability? 
Desktop systems that are used to store and read e-mail are particularly at risk from this vulnerability.

What does the update do? 
The update addresses this vulnerability by correctly validating responses returned by the e-mail server prior to processing.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.

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 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.

For more information about the installer, visit the Microsoft TechNet Web site.

    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.

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.

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.
