Microsoft Security Bulletin MS07-035 - Critical

Vulnerability in Win 32 API Could Allow Remote Code Execution (935839)

Published: June 12, 2007

Version: 1.0

General Information

Executive Summary

This critical security update resolves a privately reported vulnerability in a Win32 API. This vulnerability could allow remote code execution or elevation of privilege if the affected API is used locally by a specially crafted application. Therefore applications that use this component of the Win32 API could be used as a vector for this vulnerability. For example, Internet Explorer uses this Win32 API function when parsing specially crafted Web pages.

This is a critical security update for all supported versions of Windows 2000, Windows XP, and Windows Server 2003. For more information, see the subsection, Affected and Non-Affected Software, in this section.

This security update addresses the vulnerability by changing the way the Win32 API validates parameters. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Remote Code Execution

Critical

A remote code execution vulnerability exists in the way that the Win32 API validates parameters. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could potentially allow remote code execution if a user viewed the Web page. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2007-2219.

Mitigating Factors for Win32 API Vulnerability - CVE-2007-2219

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:

  • In a Web-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability. In addition, Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.
  • 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.

Workarounds for Win32 API Vulnerability - CVE-2007-2219

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:

Read e-mail messages in plain text format to help protect yourself from the HTML e-mail attack vector

You can help protect yourself against this vulnerability by changing your e-mail settings to read e-mail messages in plain text using Outlook 2002 and later, Outlook Express 6 and later, or Windows Mail. For information in Outlook, search “plain text” in Help and review “Read messages in plain text.” In Outlook Express, search “plain text” in Help and review “Reducing your risk of getting e-mail viruses.” In Windows Mail, search “plain text” in Help and review “Security and privacy in Windows Mail.”

Impact of Workaround: E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Additionally:

  • The changes are applied to the preview pane and to open messages.
  • Pictures become attachments so that they are not lost.
  • Because the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.

FAQ for Win32 API Vulnerability - CVE-2007-2219

What is the scope of the vulnerability?
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could remotely 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 Win32 API does not correctly validate parameters passed to it in a function call.

What is the Win 32 API? 
The Microsoft Win 32 application programming interface (API) provides 32-bit services used by all Windows-based applications. You can provide your application with a graphical user interface; access system resources such as memory and devices; display graphics and formatted text; incorporate audio, video, networking, or security. For more information, see the Microsoft Developer Network.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could take complete control of the affected system.

How could an attacker exploit the vulnerability?
An attacker could host a specially crafted Web site that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the Web site. This can also include Web sites that accept user-provided content or advertisements, Web sites that host user-provided content or advertisements, and compromised Web sites. These Web sites could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger request that takes users to the attacker's Web site.

What systems are primarily at risk from the vulnerability?
This vulnerability requires that a user either be logged on locally and run a specially crafted application or that a user be logged on and visits a Web site for any malicious action to occur.

Therefore, any systems where Internet Explorer or multiple users have permissions to log on locally is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability.

What does the update do?
The update removes the vulnerability by modifying the way that the Win API validates parameters passed to it in a function call.

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.

Deployment Information

Installing the Update

When you install this security update, the installer checks to see if 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 any applicable 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 Package 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.

This security update supports the following setup switches.

Supported Security Update Installation Switches
SwitchDescription
/helpDisplays the command-line options
Setup Modes
/passiveUnattended Setup mode. No user interaction is required, but installation status is displayed. If a restart is required at the end of Setup, a dialog box will be presented to the user with a timer warning that the system will restart in 30 seconds.
/quietQuiet mode. This is the same as unattended mode, but no status or error messages are displayed.
Restart Options
/norestartDoes not restart when installation has completed
/forcerestartRestarts the system after installation and force other applications to close at shutdown without saving open files first.
/warnrestart[:x]Presents a dialog box with a timer warning the user that the system will restart in x seconds. (The default setting is 30 seconds.) Intended for use with the /quiet switch or the /passive switch.
/promptrestartDisplay a dialog box prompting the local user to allow a restart
Special Options
/overwriteoemOverwrites OEM files without prompting
/nobackupDoes not back up files needed for uninstall
/forceappscloseForces other programs to close when the system shuts down
/log:pathAllows the redirection of installation log files
/integrate:pathIntegrates the update into the Windows source files. These files are located at the path that is specified in the switch.
/extract[:path]Extracts files without starting the Setup program
/EREnables extended error reporting
/verboseEnables verbose logging. During installation, creates %Windir%\CabBuild.log. This log details the files that are copied. Using this switch may cause the installation to proceed more slowly.

Note You can combine these switches into one command. For backward compatibility, the security update also supports many of the setup switches that the earlier version of the Setup program uses. For more information about the supported installation switches, see Microsoft Knowledge Base Article 262841. For more information about the Package Installer, visit the Microsoft TechNet Web site.

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 and 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 version of the operating system or programs installed, 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.
