VSD File Format Memory Corruption Vulnerability - CVE-2012-0018 --------------------------------------------------------------- A remote code execution vulnerability exists in the way that Microsoft Visio validates attributes when handling specially crafted Visio files. 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. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see [CVE-2012-0018](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-0018). #### Mitigating Factors for VSD File Format Memory Corruption Vulnerability - CVE-2012-0018 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: - By default, all supported versions of Microsoft Outlook, Microsoft Outlook Express, and Windows Mail open HTML email messages in the Restricted sites zone. The Restricted sites zone, which disables script and ActiveX controls, helps reduce the risk of an attacker being able to use this vulnerability to execute malicious code. If a user clicks a link in an email message, the user could still be vulnerable to exploitation of this vulnerability through the web-based attack scenario. - By default, Internet Explorer on Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 runs in a restricted mode that is known as [Enhanced Security Configuration](http://technet.microsoft.com/en-us/library/dd883248(ws.10).aspx). This mode mitigates this vulnerability. See the FAQ section for this vulnerability for more information about Internet Explorer Enhanced Security Configuration. - In a web-based attack scenario, an attacker could host a website that contains a specially crafted Visio file that is used to attempt to exploit this vulnerability. In addition, compromised websites and websites 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 websites. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes users to the attacker’s website, and convince them to open the specially crafted Visio file. - An attacker who successfully exploited this vulnerability could gain the same user rights as the current 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 VSD File Format Memory Corruption Vulnerability - CVE-2012-0018 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: - **Set Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones** You can help protect against exploitation of this vulnerability by changing your settings for the Internet security zone to block ActiveX controls and Active Scripting. You can do this by setting your browser security to High. To raise the browsing security level in Internet Explorer, perform the following steps: 1. On the Internet Explorer **Tools** menu, click **Internet Options**. 2. In the **Internet Options** dialog box, click the **Security** tab, and then click the **Internet** icon. 3. Under **Security level for this zone**, move the slider to **High**, and then click **OK**. This sets the security level for all websites you visit to High. **Note** If no slider is visible, click **Default Level**, and then move the slider to **High**, and then click **OK**. **Note** Setting the level to High may cause some websites to work incorrectly. If you have difficulty using a website after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly even with the security setting set to High. **Impact of workaround.** There are side effects to blocking ActiveX Controls and Active Scripting. Many websites that are on the Internet or on an intranet use ActiveX or Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use ActiveX Controls to provide menus, ordering forms, or even account statements. Blocking ActiveX Controls or Active Scripting is a global setting that affects all Internet and intranet sites. If you do not want to block ActiveX Controls or Active Scripting for such sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone". **Add sites that you trust to the Internet Explorer Trusted sites zone** After you set Internet Explorer to block ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted websites exactly as you do today, while helping to protect yourself from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone. To do this, perform the following steps: 1. In Internet Explorer, click **Tools**, click **Internet Options**, and then click the **Security** tab. 2. In the **Select a** **web content zone to specify its current security settings** box, click **Trusted Sites**, and then click **Sites**. 3. If you want to add sites that do not require an encrypted channel, click to clear the **Require server verification (https:) for all sites in this zone** check box. 4. In the **Add this** **website to the zone** box, type the URL of a site that you trust, and then click **Add**. 5. Repeat these steps for each site that you want to add to the zone. 6. Click **OK** two times to accept the changes and return to Internet Explorer. **Note** Add any sites that you trust not to take malicious action on your system. Two in particular that you may want to add are **\*.windowsupdate.microsoft.com** and **\*.update.microsoft.com**. These are the sites that will host the update, and it requires an ActiveX Control to install the update. - **Configure Internet Explorer to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone** You can help protect against exploitation of this vulnerability by changing your settings to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone. To do this, perform the following steps: 1. In Internet Explorer, click **Internet Options** on the **Tools** menu. 2. Click the **Security** tab. 3. Click **Internet**, and then click **Custom Level**. 4. Under **Settings**, in the **Scripting** section, under **Active Scripting**, click **Prompt** or **Disable**, and then click **OK**. 5. Click **Local intranet**, and then click **Custom Level**. 6. Under **Settings**, in the **Scripting** section, under **Active Scripting**, click **Prompt** or **Disable**, and then click **OK**. 7. Click **OK** two times to return to Internet Explorer. **Note** Disabling Active Scripting in the Internet and Local intranet security zones may cause some websites to work incorrectly. If you have difficulty using a website after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly. **Impact of workaround.** There are side effects to prompting before running Active Scripting. Many websites that are on the Internet or on an intranet use Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use Active Scripting to provide menus, ordering forms, or even account statements. Prompting before running Active Scripting is a global setting that affects all Internet and intranet sites. You will be prompted frequently when you enable this workaround. For each prompt, if you feel you trust the site that you are visiting, click **Yes** to run Active Scripting. If you do not want to be prompted for all these sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone". **Add sites that you trust to the Internet Explorer Trusted sites zone** After you set Internet Explorer to require a prompt before it runs ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted websites exactly as you do today, while helping to protect you from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone. To do this, perform the following steps: 1. In Internet Explorer, click **Tools**, click **Internet Options**, and then click the **Security** tab. 2. In the **Select a** **web content zone to specify its current security settings** box, click **Trusted Sites**, and then click **Sites**. 3. If you want to add sites that do not require an encrypted channel, click to clear the **Require server verification (https:) for all sites in this zone** check box. 4. In the **Add this** **website to the zone** box, type the URL of a site that you trust, and then click **Add**. 5. Repeat these steps for each site that you want to add to the zone. 6. Click **OK** two times to accept the changes and return to Internet Explorer. **Note** Add any sites that you trust not to take malicious action on your system. Two in particular that you may want to add are **\*.windowsupdate.microsoft.com** and **\*.update.microsoft.com**. These are the sites that will host the update, and it requires an ActiveX Control to install the update. - **Do not open Office files that you receive from untrusted sources or that you receive unexpectedly from trusted sources** Do not open Office files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file. #### FAQ for VSD File Format Memory Corruption Vulnerability - CVE-2012-0018 **What is the scope of the vulnerability?**  This is a remote code execution vulnerability. **What causes the vulnerability?**  The vulnerability exists when Microsoft Visio does not properly handle memory when parsing specially crafted Visio files. **What might an attacker use the vulnerability to do?**  An attacker who successfully exploited this vulnerability could run arbitrary code in the context of the current user. If the current 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?**  This vulnerability requires that a user open a specially crafted Visio file with an affected version of Microsoft Visio Viewer. In an email attack scenario, an attacker could exploit the vulnerability by sending a specially crafted Visio file to the user and by convincing the user to open the file. In a web-based attack scenario, an attacker would have to host a website that contains a specially crafted Visio file that is used to attempt to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link that takes them to the attacker's site, and then convince them to open a specially crafted Visio file. **What systems are primarily at risk from the vulnerability?**  Systems where Microsoft Visio is used, including 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?**  This update addresses the vulnerability by modifying the way that Microsoft Visio Viewer validates data when parsing specially crafted Visio files. **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. ### Update Information Detection and Deployment Tools and Guidance ------------------------------------------- **Security Central** Manage the software and security updates you need to deploy to the servers, desktop, and mobile systems in your organization.

Note When you remove this update, you may be prompted to insert the 2007 Microsoft Office CD in the CD drive. Additionally, you may not have the option to uninstall the update from the Add or Remove Programs item in Control Panel. There are several possible causes for this issue. For more information about the removal, see Microsoft Knowledge Base Article 903771.

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.

    1. Click Start and then enter an update file name in the Start Search box.
    2. When the file appears under Programs, right-click the file name and click Properties.
    3. 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 files that are listed in the file information table may not be installed.
    4. 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.
    5. 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.
