General Information
Executive Summary
This security update resolves ten privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the most severe of these vulnerabilities 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.
This security update is rated Critical for Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, and Internet Explorer 11 on affected Windows clients and Important for Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, and Internet Explorer 10 on affected Windows servers. In addition, for Internet Explorer 11 on affected Windows servers, this security update is rated Moderate. 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 Internet Explorer handles CSS special characters, handles specially crafted web content when generating print previews, and handles objects in memory. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Recommendation. Most 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.

Internet Explorer Information Disclosure Vulnerability - CVE-2013-3908
An information disclosure vulnerability exists in the way that Internet Explorer handles specially crafted web content when generating print previews. An attacker who successfully exploited this vulnerability could gather information from any page that the victim is viewing.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2013-3908.
Mitigating Factors
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 take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email message or in an Instant Messenger message that takes users to the attacker's website, or by getting them to open an attachment sent through email.
Workarounds
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:
Do not use the Print Preview feature in Internet Explorer
Do not use the Print Preview feature. If prompted to initiate a print preview, select No or Cancel.
Note This workaround addresses the attack vector where an attacker attempts to trick or convince a potential victim into initiating a print preview. This workaround must be used in conjunction with one of the following workarounds to address all known attack vectors:
- Set Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones
- Configure Internet Explorer to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone
Set Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones
Note This workaround addresses attack vectors that utilize active scripting. This workaround must be used in conjunction with the Do not use the Print Preview feature in Internet Explorer workaround to address all known attack vectors.
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:
- On the Internet Explorer Tools menu, click Internet Options.
- In the Internet Options dialog box, click the Security tab, and then click Internet.
- Under Security level for this zone, move the slider to High. This sets the security level for all websites you visit to High.
- Click Local intranet.
- Under Security level for this zone, move the slider to High. This sets the security level for all websites you visit to High.
- Click OK to accept the changes and return to Internet Explorer.
Note If no slider is visible, click Default Level, and then move the slider to High.
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:
- In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
- In the Select a web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
- 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.
- In the Add this website to the zone box, type the URL of a site that you trust, and then click Add.
- Repeat these steps for each site that you want to add to the zone.
- 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
Note This workaround addresses attack vectors that utilize active scripting. This workaround must be used in conjunction with the Do not use the Print Preview feature in Internet Explorer workaround to address all known attack vectors.
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:
- In Internet Explorer, click Internet Options on the Tools menu.
- Click the Security tab.
- Click Internet, and then click Custom Level.
- Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
- Click Local intranet, and then click Custom Level.
- Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
- 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:
- In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
- In the Select a web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
- 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.
- In the Add this website to the zone box, type the URL of a site that you trust, and then click Add.
- Repeat these steps for each site that you want to add to the zone.
- 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.

FAQ
What is the scope of the vulnerabilities?
These are remote code execution vulnerabilities in the context of the current user.
What causes the vulnerabilities?
When Internet Explorer improperly accesses objects in memory, it could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.
What might an attacker use the vulnerabilities to do?
An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited these vulnerabilities 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.
How could an attacker exploit the vulnerabilities?
An attacker could host a specially crafted website that is designed to exploit these vulnerabilities through Internet Explorer, and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit these vulnerabilities. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email message or in an Instant Messenger message that takes users to the attacker's website, or by getting them to open an attachment sent through email.
