Microsoft Security Bulletin MS14-021 - Critical
Security Update for Internet Explorer (2965111)
Published: May 1, 2014
Version: 1.1
General Information
Executive Summary
This security update resolves a publicly disclosed vulnerability in Internet Explorer. The vulnerability could allow remote code execution if a user views a specially crafted webpage using an affected version of Internet Explorer. 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.
This security update is rated Critical for Internet Explorer 6 (IE 6), Internet Explorer 7 (IE 7), Internet Explorer 8 (IE 8), Internet Explorer 9 (IE 9), Internet Explorer 10 (IE 10), and Internet Explorer 11 (IE 11) on affected Windows clients, and Moderate for Internet Explorer 6 (IE 6), Internet Explorer 7 (IE 7), Internet Explorer 8 (IE 8), Internet Explorer 9 (IE 9), Internet Explorer 10 (IE 10), and Internet Explorer 11 (IE 11) on affected Windows servers. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by modifying the way that Internet Explorer handles objects in memory. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry later in this bulletin.
This security update addresses the vulnerability first described in Microsoft Security Advisory 2963983.
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. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871. For Customers who do not have automatic updating enabled, the steps in Turn automatic updating on or off can be used to enable automatic updating.
For administrators and enterprise installations, or end users who want to install this security update manually (including customers who have not enabled automatic updating), Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service. The updates are also available via the download links in the Affected Software table later in this bulletin.

Update FAQ
There are multiple updates listed for Internet Explorer 11. Do I need to install all the updates?
No. Depending on how your system is configured to receive updates, only one of the updates for Internet Explorer 11 may apply.
For systems running Internet Explorer 11 on Windows 7 or Windows Server 2008 R2:
- The 2964358 update is for systems that have the 2929437 update installed.
- The 2964444 update is for systems without the 2929437 update installed.
For systems running Internet Explorer 11 on Windows 8.1, Windows Server 2012 R2, or Windows RT 8.1:
- The 2964358 update is for systems that have the 2919355 update installed.
- The 2964444 update is for systems without the 2919355 update installed.
For Internet Explorer 11, are there any prerequisites for the 2964358 update?
Yes. Customers running Internet Explorer 11 on Windows 8.1, Windows Server 2012 R2, or Windows RT 8.1, must first install the 2919355 update released in April, 2014 before installing the 2964358 update. For more information about this prerequisite update, see Microsoft Knowledge Base Article 2919355.
Customers running Internet Explorer 11 on Windows 7 or Windows Server 2008 R2, must first install the 2929437 update released in April, 2014 before installing the 2964358 update. For more information about this prerequisite update, see Microsoft Knowledge Base Article 2929437.
Is this update, MS14-021, a cumulative security update for Internet Explorer?
No. This security update, MS14-021, only addresses the vulnerability described in this bulletin.
Do I need to install the last cumulative security update for Internet Explorer?
Yes. This security update, MS14-021, is not a cumulative security update. Customers who have not installed the latest cumulative security update for Internet Explorer are likely to experience compatibility issues, such as Internet Explorer may intermittently stop responding, after installing the MS14-021 update.
Note that the order of installation does matter. To avoid compatibility issues, the MS14-021 security update must be installed after installing the latest cumulative security update for Internet Explorer.
Refer to the following table for details:
Version of Internet Explorer | Latest cumulative update that must be applied prior to installing the MS14-021 update |
---|---|
Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, and Internet Explorer 9 on all supported releases of Microsoft Windows | MS14-018 |
Internet Explorer 10 on all supported releases of Microsoft Windows | MS14-018 (note that this was a non-security update for Internet Explorer 10) |
Internet Explorer 11 on Windows 7 or Windows Server 2008 R2 | For the 2964444 update: MS14-012 (note that MS14-018 was not a cumulative update for Internet Explorer 11) For the 2964358 update: 2929437 |
Internet Explorer 11 on Windows 8.1, Windows Server 2012 R2, or Windows RT 8.1 | For the 2964444 update: MS14-012 (note that MS14-018 was not a cumulative update for Internet Explorer 11) For the 2964358 update: 2919355 |
If you applied the workaround to modify the Access Control List (ACL) on VGX.DLL, then you must undo this workaround before applying this security update. To undo this workaround, from an elevated command prompt, run the following command:
echo y| cacls "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll" /g original ACLs
where original ACLs are the original user access rights before the workaround was applied. Alternatively, the access to vgx.dll could be set to everyone using the following command from an elevated command prompt:
echo y| cacls "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll" /E /R everyone
You should repeat the above for "%CommonProgramFiles(x86)%\Microsoft Shared\VGX\vgx.dll" on 64-bit systems. Also note that if icacls was used instead of cacls to apply the workaround, then use icacls to restore the original ACLs.
For example, these commands for icacls could be run from an elevated command prompt:
icacls "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll" /grant everyone:(F) icacls "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll" /restore %TEMP%\VGX_ACL.TXT
where VGX_ACL.TXT is the backup file created to save the original user access rights when the workaround was applied using icacls.
You should repeat the above for "%CommonProgramFiles(x86)%\Microsoft Shared\VGX\vgx.dll" on 64-bit systems.
If you applied the workaround to unregister VGX.DLL, you do not have to undo this workaround before applying the security update. However, the security update will not re-register vgx.dll. See the Workarounds section for the vulnerability for steps on how to re-register vgx.dll.
Note For users running 64-bit systems who applied the original unregister VGX.DLL workaround documented in version 1.0 of Microsoft Security Advisory 2963983, please apply the updated workaround as described in this security bulletin for 64-bit systems.
If you applied any of the other workarounds from Microsoft Security Advisory 2963983, you do not have to undo the workaround before applying the security update.
How are Server Core installations affected by the vulnerability addressed in this bulletin?
The vulnerability addressed by this update do not affect supported editions of Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, or Windows Server 2012 R2 as indicated in the Non-Applicable Software table, when installed using the Server Core installation option.
