Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.\n\n**Set web browser security to disable the execution of script code or active content.** \nSince a successful exploit of these issues requires malicious code to execute in web clients, consider disabling support for script code and active content within the client browser. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.\n\n**Implement multiple redundant layers of security.** \nVarious memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.\n\nThe vendor has released an advisory and updates.

Information\r\nExecutive Summary\r\n\r\nThis security update resolves four privately reported vulnerabilities and three publicly disclosed vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. 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.\r\n\r\nThis security update is rated Critical for Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8. For more information, see the subsection, Affected and Non-Affected Software, in this section.\r\n\r\nThe security update addresses the vulnerabilities by modifying the way that Internet Explorer handles objects in memory and script during certain processes. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.\r\n\r\nThis security update also addresses the vulnerability first described in Microsoft Security Advisory 2458511.\r\n\r\nRecommendation. The majority of 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.\r\n\r\nFor administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service.\r\n\r\nSee also the section, Detection and Deployment Tools and Guidance, later in this bulletin.\r\n\r\nKnown Issues. Microsoft Knowledge Base Article 2416400 documents the currently known issues that customers may experience when installing this security update. The article also documents recommended solutions for these issues.\r\nTop of sectionTop of section\r\nAffected and Non-Affected Software\r\n\r\nThe following software have been tested to determine which versions or editions are affected.

However, as a defense-in-depth measure to protect against any possible new vectors identified in the future, Microsoft recommends that customers of this software apply this security update.\r\nTop of sectionTop of section\r\n\t\r\nHTML Object Memory Corruption Vulnerability - CVE-2010-3340\r\n\r\nA remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. 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 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.\r\n\r\nTo view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-3340.\r\n\t\r\nMitigating Factors for HTML Object Memory Corruption Vulnerability - CVE-2010-3340\r\n\r\nMitigation 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:\r\n\u2022\t\r\n\r\nAn 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.\r\n\u2022\t\r\n\r\nIn 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, compromised Web sites and 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.\r\n\u2022\t\r\n\r\nBy default, all supported versions of Microsoft Outlook, Microsoft Outlook Express, and Windows Mail open HTML e-mail messages in the Restricted sites zone, which disables script and ActiveX controls, removing the risk of an attacker being able to use this vulnerability to execute malicious code. If a user clicks a link in an e-mail message, the user could still be vulnerable to exploitation of this vulnerability through the Web-based attack scenario.\r\n\u2022\t\r\n\r\nBy default, Internet Explorer on Windows Server 2003 and Windows Server 2008 runs in a restricted mode that is known as Enhanced Security Configuration. This mode sets the security level for the Internet zone to High. This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone. See the FAQ subsection of this vulnerability section for more information about Internet Explorer Enhanced Security Configuration.\r\nTop of sectionTop of section\r\n\t\r\nWorkarounds for HTML Object Memory Corruption Vulnerability - CVE-2010-3340\r\n\r\nWorkaround 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:\r\n\u2022\t\r\n\r\nSet Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones\r\n\r\nYou 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.\r\n\r\nTo raise the browsing security level in Internet Explorer, follow these steps:\r\n\r\n1.\r\n\t\r\n\r\nOn the Internet Explorer Tools menu, click Internet Options.\r\n\r\n2.\r\n\t\r\n\r\nIn the Internet Options dialog box, click the Security tab, and then click the Internet icon.\r\n\r\n3.\r\n\t\r\n\r\nUnder Security level for this zone, move the slider to High. This sets the security level for all Web sites you visit to High.\r\n\r\nNote If no slider is visible, click Default Level, and then move the slider to High.\r\n\r\nNote Setting the level to High may cause some Web sites to work incorrectly. If you have difficulty using a Web site 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.\r\n\r\nImpact of workaround. There are side effects to blocking ActiveX Controls and Active Scripting. Many Web sites 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.

An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on 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.\r\n\r\nWhat causes the vulnerability? \r\nWhen Internet Explorer attempts to access incorrectly initialized memory under certain conditions, it may corrupt memory in such a way that an attacker could execute arbitrary code.\r\n\r\nWhat might an attacker use the vulnerability to do? \r\nAn attacker who successfully exploited this vulnerability could gain the same user rights as a logged-on user. If the user is logged on with administrative user rights, 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.\r\n\r\nHow could an attacker exploit the vulnerability? \r\nAn 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. The attacker could also take advantage of compromised Web sites and Web sites that accept or host user-provided content or advertisements. 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 message that takes users to the attacker's Web site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nThis vulnerability requires that a user be logged on and visiting a Web site for any malicious action to occur. Therefore, any systems where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability.\r\n\r\nI am running Internet Explorer for Windows Server 2003 or Windows Server 2008. Does this mitigate this vulnerability? \r\nYes. By default, Internet Explorer on Windows Server 2003 and Windows Server 2008 runs in a restricted mode that is known as Enhanced Security Configuration. Enhanced Security Configuration is a group of preconfigured settings in Internet Explorer that can reduce the likelihood of a user or administrator downloading and running specially crafted Web content on a server. This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone. See also Managing Internet Explorer Enhanced Security Configuration.\r\n\r\nWhat does the update do? \r\nThe update addresses the vulnerability by modifying the way that Internet Explorer handles objects in memory.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed? \r\nNo. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.\r\n\r\nWhen this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? \r\nNo. 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.\r\nTop of sectionTop of section\r\nTop of sectionTop of section\r\n\t\r\nCross-Domain Information Disclosure Vulnerability - CVE-2010-3342\r\n\r\nAn information disclosure vulnerability exists in Internet Explorer that could allow script to gain access to information in another domain or Internet Explorer zone. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could allow information disclosure if a user viewed the Web page. An attacker who successfully exploited this vulnerability could view content from another domain or Internet Explorer zone.\r\n\r\nTo view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-3342.\r\n\t\r\nMitigating Factors for Cross-Domain Information Disclosure Vulnerability - CVE-2010-3342\r\n\r\nMitigation 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:\r\n\u2022\t\r\n\r\nBy default, Internet Explorer on Windows Server 2003 and Windows Server 2008 runs in a restricted mode that is known as Enhanced Security Configuration. This mode sets the security level for the Internet zone to High. This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone. See the FAQ subsection of this vulnerability section for more information about Internet Explorer Enhanced Security Configuration.\r\n\u2022\t\r\n\r\nBy default, all supported versions of Microsoft Outlook, Microsoft Outlook Express, and Windows Mail open HTML e-mail messages in the Restricted sites zone, which disables script and ActiveX controls, removing the risk of an attacker being able to use this vulnerability to execute malicious code. If a user clicks a link in an e-mail message, the user could still be vulnerable to exploitation of this vulnerability through the Web-based attack scenario.\r\n\u2022\t\r\n\r\nAn 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.\r\nTop of sectionTop of section\r\n\t\r\nWorkarounds for Cross-Domain Information Disclosure Vulnerability - CVE-2010-3342\r\n\r\nWorkaround 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:\r\n\u2022\t\r\n\r\nRead e-mails in plain text\r\n\r\nTo help protect yourself from the e-mail attack vector, read e-mail messages in plain text format.\r\n\r\nMicrosoft Office Outlook 2002 users who have applied Office XP Service Pack 1 or a later version and Microsoft Office Outlook Express 6 users who have applied Internet Explorer 6 Service Pack 1 or a later version can enable this setting and view e-mail messages that are not digitally signed or e-mail messages that are not encrypted in plain text only.\r\n\r\nDigitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about how to enable this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.\r\n\r\nFor information about this setting in Outlook Express 6, see Microsoft Knowledge Base Article 291387.\r\n\r\nImpact of workaround. E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Additionally:\r\n\u2022\t\r\n\r\nThe changes are applied to the preview pane and to open messages.\r\n\u2022\t\r\n\r\nPictures become attachments so that they are not lost.\r\n\u2022\t\r\n\r\nBecause the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.\r\n\u2022\t\r\n\r\nSet Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones\r\n\r\nYou can help protect against exploitation of this vulnerability by changing your settings for the Internet security zone to block ActiveX controls and Active Scripting.

An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on 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.\r\n\r\nWhat causes the vulnerability? \r\nWhen Internet Explorer attempts to access incorrectly initialized memory under certain conditions, it may corrupt memory in such a way that an attacker could execute arbitrary code.\r\n\r\nWhat might an attacker use the vulnerability to do? \r\nAn attacker who successfully exploited this vulnerability could gain the same user rights as a logged-on user. If the user is logged on with administrative user rights, 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.\r\n\r\nHow could an attacker exploit the vulnerability? \r\nAn 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. The attacker could also take advantage of compromised Web sites and Web sites that accept or host user-provided content or advertisements. 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 message that takes users to the attacker's Web site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nThis vulnerability requires that a user be logged on and visiting a Web site for any malicious action to occur. Therefore, any systems where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability.\r\n\r\nI am running Internet Explorer for Windows Server 2003 or Windows Server 2008. Does this mitigate this vulnerability? \r\nYes. By default, Internet Explorer on Windows Server 2003 and Windows Server 2008 runs in a restricted mode that is known as Enhanced Security Configuration. Enhanced Security Configuration is a group of preconfigured settings in Internet Explorer that can reduce the likelihood of a user or administrator downloading and running specially crafted Web content on a server. This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone. See also Managing Internet Explorer Enhanced Security Configuration.\r\n\r\nWhat does the update do? \r\nThe update addresses the vulnerability by modifying the way that Internet Explorer handles objects in memory.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed? \r\nNo. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.\r\n\r\nWhen this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? \r\nNo. 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.\r\nTop of sectionTop of section\r\nTop of sectionTop of section\r\n\t\r\nHTML Element Memory Corruption Vulnerability - CVE-2010-3345\r\n\r\nA remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. 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 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.\r\n\r\nTo view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-3345.\r\n\t\r\nMitigating Factors for HTML Element Memory Corruption Vulnerability - CVE-2010-3345\r\n\r\nMitigation 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:\r\n\u2022\t\r\n\r\nIn 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, compromised Web sites and 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.\r\n\u2022\t\r\n\r\nAn 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.\r\n\u2022\t\r\n\r\nBy default, all supported versions of Microsoft Outlook, Microsoft Outlook Express, and Windows Mail open HTML e-mail messages in the Restricted sites zone, which disables script and ActiveX controls, removing the risk of an attacker being able to use this vulnerability to execute malicious code. If a user clicks a link in an e-mail message, the user could still be vulnerable to exploitation of this vulnerability through the Web-based attack scenario.\r\n\u2022\t\r\n\r\nBy default, Internet Explorer on Windows Server 2003 and Windows Server 2008 runs in a restricted mode that is known as Enhanced Security Configuration.

To do this, follow these steps:\r\n\r\n1.\r\n\t\r\n\r\nIn Internet Explorer, click Internet Options on the Tools menu.\r\n\r\n2.\r\n\t\r\n\r\nClick the Security tab.\r\n\r\n3.\r\n\t\r\n\r\nClick Internet, and then click Custom Level.\r\n\r\n4.\r\n\t\r\n\r\nUnder Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.\r\n\r\n5.\r\n\t\r\n\r\nClick Local intranet, and then click Custom Level.\r\n\r\n6.\r\n\t\r\n\r\nUnder Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.\r\n\r\n7.\r\n\t\r\n\r\nClick OK two times to return to Internet Explorer.\r\n\r\nNote Disabling Active Scripting in the Internet and Local intranet security zones may cause some Web sites to work incorrectly. If you have difficulty using a Web site 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.\r\n\r\nImpact of workaround. There are side effects to prompting before running Active Scripting. Many Web sites 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".\r\n\r\nAdd sites that you trust to the Internet Explorer Trusted sites zone\r\n\r\nAfter 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 Web sites 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.\r\n\r\nTo do this, follow these steps:\r\n\r\n1.\r\n\t\r\n\r\nIn Internet Explorer, click Tools, click Internet Options, and then click the Security tab.\r\n\r\n2.\r\n\t\r\n\r\nIn the Select a Web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.\r\n\r\n3.\r\n\t\r\n\r\nIf 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.\r\n\r\n4.\r\n\t\r\n\r\nIn the Add this Web site to the zone box, type the URL of a site that you trust, and then click Add.\r\n\r\n5.\r\n\t\r\n\r\nRepeat these steps for each site that you want to add to the zone.\r\n\r\n6.\r\n\t\r\n\r\nClick OK two times to accept the changes and return to Internet Explorer.\r\n\r\nNote Add any sites that you trust not to take malicious action on your system.

An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on 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.\r\n\r\nWhat causes the vulnerability? \r\nWhen Internet Explorer attempts to access incorrectly initialized memory under certain conditions, it may corrupt memory in such a way that an attacker could execute arbitrary code.\r\n\r\nWhat might an attacker use the vulnerability to do? \r\nAn attacker who successfully exploited this vulnerability could gain the same user rights as a logged-on user. If the user is logged on with administrative user rights, 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.\r\n\r\nHow could an attacker exploit the vulnerability? \r\nAn 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. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised Web sites and Web sites that accept or host user-provided content or advertisements. 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 view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by clicking a link in an e-mail message or in an Instant Messenger message that takes users to the attacker's Web site, or by opening an attachment sent through e-mail.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nThis vulnerability requires that a user be logged on and visiting a Web site for any malicious action to occur. Therefore, any systems where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability.\r\n\r\nI am running Internet Explorer for Windows Server 2003 or Windows Server 2008. Does this mitigate this vulnerability? \r\nYes. By default, Internet Explorer on Windows Server 2003 and Windows Server 2008 runs in a restricted mode that is known as Enhanced Security Configuration. Enhanced Security Configuration is a group of preconfigured settings in Internet Explorer that can reduce the likelihood of a user or administrator downloading and running specially crafted Web content on a server. This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone. See also Managing Internet Explorer Enhanced Security Configuration.\r\n\r\nWhat does the update do? \r\nThe update addresses the vulnerability by modifying the way that Internet Explorer handles objects in memory.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed? \r\nNo. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.\r\n\r\nWhen this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? \r\nNo. 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.\r\nTop of sectionTop of section\r\nTop of sectionTop of section\r\n\t\r\nCross-Domain Information Disclosure Vulnerability - CVE-2010-3348\r\n\r\nAn information disclosure vulnerability exists in Internet Explorer that could allow script to gain access to information in another domain or Internet Explorer zone. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could allow information disclosure if a user viewed the Web page. An attacker who successfully exploited this vulnerability could view content from another domain or Internet Explorer zone.\r\n\r\nTo view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-3348.\r\n\t\r\nMitigating Factors for Cross-Domain Information Disclosure Vulnerability - CVE-2010-3348\r\n\r\nMitigation 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:\r\n\u2022\t\r\n\r\nBy default, Internet Explorer on Windows Server 2003 and Windows Server 2008 runs in a restricted mode that is known as Enhanced Security Configuration. This mode sets the security level for the Internet zone to High. This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone. See the FAQ subsection of this vulnerability section for more information about Internet Explorer Enhanced Security Configuration.\r\n\u2022\t\r\n\r\nBy default, all supported versions of Microsoft Outlook, Microsoft Outlook Express, and Windows Mail open HTML e-mail messages in the Restricted sites zone, which disables script and ActiveX controls, removing the risk of an attacker being able to use this vulnerability to execute malicious code. If a user clicks a link in an e-mail message, the user could still be vulnerable to exploitation of this vulnerability through the Web-based attack scenario.\r\nTop of sectionTop of section\r\n\t\r\nWorkarounds for Cross-Domain Information Disclosure Vulnerability - CVE-2010-3348\r\n\r\nWorkaround 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:\r\n\u2022\t\r\n\r\nRead e-mails in plain text\r\n\r\nTo help protect yourself from the e-mail attack vector, read e-mail messages in plain text format.\r\n\r\nMicrosoft Office Outlook 2002 users who have applied Office XP Service Pack 1 or a later version and Microsoft Office Outlook Express 6 users who have applied Internet Explorer 6 Service Pack 1 or a later version can enable this setting and view e-mail messages that are not digitally signed or e-mail messages that are not encrypted in plain text only.\r\n\r\nDigitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about how to enable this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.\r\n\r\nFor information about this setting in Outlook Express 6, see Microsoft Knowledge Base Article 291387.\r\n\r\nImpact of workaround. E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Additionally:\r\n\u2022\t\r\n\r\nThe changes are applied to the preview pane and to open messages.\r\n\u2022\t\r\n\r\nPictures become attachments so that they are not lost.\r\n\u2022\t\r\n\r\nBecause the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.\r\n\u2022\t\r\n\r\nSet Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones\r\n\r\nYou 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.\r\n\r\nTo raise the browsing security level in Internet Explorer, follow these steps:\r\n\r\n1.\r\n\t\r\n\r\nOn the Internet Explorer Tools menu, click Internet Options.\r\n\r\n2.\r\n\t\r\n\r\nIn the Internet Options dialog box, click the Security tab, and then click the Internet icon.\r\n\r\n3.\r\n\t\r\n\r\nUnder Security level for this zone, move the slider to High. This sets the security level for all Web sites you visit to High.\r\n\r\nNote If no slider is visible, click Default Level, and then move the slider to High.\r\n\r\nNote Setting the level to High may cause some Web sites to work incorrectly. If you have difficulty using a Web site 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.\r\n\r\nImpact of workaround. There are side effects to blocking ActiveX Controls and Active Scripting. Many Web sites 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.

An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on 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.\r\n\r\nWhat causes the vulnerability? \r\nWhen Internet Explorer attempts to access an object that has not been initialized or has been deleted, it may corrupt memory in such a way that an attacker could execute arbitrary code in the context of the logged-on user.\r\n\r\nWhat might an attacker use the vulnerability to do? \r\nAn attacker who successfully exploited this vulnerability could gain the same user rights as a logged-on user. If the user is logged on with administrative user rights, 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.\r\n\r\nHow could an attacker exploit the vulnerability? \r\nAn 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. The attacker could also take advantage of compromised Web sites and Web sites that accept or host user-provided content or advertisements. 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 message that takes users to the attacker's Web site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nThis vulnerability requires that a user be logged on and visiting a Web site for any malicious action to occur. Therefore, any systems where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability.\r\n\r\nWhat does the update do? \r\nThe update addresses the vulnerability by modifying the way that Internet Explorer handles objects in memory.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed? \r\nYes. This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CVE-2010-3962. This vulnerability was first described in Microsoft Security Advisory 2458511.\r\n\r\nWhen this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? \r\nYes. Microsoft is aware of active attacks attempting to exploit the vulnerability.\r\n\r\nDoes applying this security update help protect customers from the code, published publicly, that attempts to exploit this vulnerability? \r\nYes. This security update addresses the vulnerability that is currently being exploited. The vulnerability that has been addressed has been assigned the Common Vulnerability and Exposure number CVE-2010-3962.\r\n\r\nIf I applied workarounds provided in Microsoft Security Advisory 2458511, do I need to reverse them before applying this update? \r\nMicrosoft recommends that you undo the "Override the Web site CSS" workaround from systems where you have previously applied it, before you install this security update. However, you may leave the "Deploy the Enhanced Mitigation Experience Toolkit" (EMET) and "Enable Data Execution Prevention (DEP) for Internet Explorer 7" workarounds in place as a defense-in-depth measure.\r\n\r\nOther Information\r\nAcknowledgments\r\n\r\nMicrosoft thanks the following for working with us to help protect customers:\r\n\u2022\t\r\n\r\nAniway of VeriSign iDefense Labs for reporting the HTML Object Memory Corruption Vulnerability (CVE-2010-3340)\r\n\u2022\t\r\n\r\nNicolas Joly of VUPEN Vulnerability Research Team for reporting the HTML Object Memory Corruption Vulnerability (CVE-2010-3343)\r\n\u2022\t\r\n\r\nStephen Fewer, working with TippingPoint's Zero Day Initiative, for reporting the HTML Element Memory Corruption Vulnerability (CVE-2010-3345)\r\n\u2022\t\r\n\r\nPeter Vreugdenhil, working with TippingPoint's Zero Day Initiative, for reporting the HTML Element Memory Corruption Vulnerability (CVE-2010-3346)\r\n\u2022\t\r\n\r\nYosuke Hasegawa for working with us on the Cross-Domain Information Disclosure Vulnerability (CVE-2010-3348)\r\n\u2022\t\r\n\r\nJose Antonio Vazquez Gonzalez of VeriSign iDefense Labs for reporting the Uninitialized Memory Corruption Vulnerability (CVE-2010-3962)\r\nTop of sectionTop of section\r\nMicrosoft Active Protections Program (MAPP)\r\n\r\nTo improve security protections for customers, Microsoft provides vulnerability information to major security software providers in advance of each monthly security update release.

BACKGROUND\r\n\r\nInternet Explorer is a graphical web browser developed by Microsoft\r\nCorp. that has been included with Microsoft Windows since 1995. For\r\nmore information about Internet Explorer, please the visit following\r\nwebsite:\r\n\r\nhttp://www.microsoft.com/ie/\r\n\r\nII. DESCRIPTION\r\n\r\nRemote exploitation of a memory corruption vulnerability in Microsoft\r\nCorp.'s Internet Explorer could allow an attacker to execute arbitrary\r\ncode with the privileges of the current user. <BR> <BR> T During the\r\ninstantiation of multiple ActiveX Controls, a particular object is\r\ncreated along with multiple references that point to the object. The\r\nobject can be destroyed and its associated references removed. However,\r\na reference can incorrectly remain pointing to the object. The invalid\r\nobject resides in uninitialized memory, which the attacker may control\r\nto gain arbitrary execution control.\r\n\r\nIII. ANALYSIS\r\n\r\nExploitation of this vulnerability results in the execution of arbitrary\r\ncode with the privileges of the user viewing the web page. To exploit\r\nthis vulnerability, a targeted user must load a malicious webpage\r\ncreated by an attacker. An attacker typically accomplishes this via\r\nsocial engineering or injecting content into a compromised, trusted\r\nsite.\r\n\r\nIV. DETECTION\r\n\r\nMicrosoft Internet Explorer 6, 7 and 8 are vulnerable.\r\n\r\nV. WORKAROUND\r\n\r\nMicrosoft suggested workarounds can be found in Microsoft Security\r\nBulletin MS10-090.\r\n\r\nVI.
