Published: March 10, 2015 | Updated: March 26, 2015
Version: 1.1
Executive Summary
This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
This security update is rated Critical for all supported editions of Microsoft Office 2007, Microsoft Office 2010, and Microsoft Office 2013. This security update is rated Important for the following affected software:
- Microsoft Excel 2007, Microsoft PowerPoint 2007, Microsoft Word 2007

Vulnerability Information
Microsoft Office Component Use After Free Vulnerability - CVE-2015-0085
A remote code execution vulnerability exists in Microsoft Office software that is caused when the Office software improperly handles objects in memory while parsing specially crafted Office files. This could corrupt system memory in such a way as to allow an attacker to execute arbitrary code.
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.
Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario an attacker could exploit the vulnerability by sending a specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to visit it, typically by getting them to click a link in an instant messenger or email message, and then convince them to open the specially crafted file.
The security update addresses the vulnerability by correcting how Microsoft Office parses specially crafted files.
Microsoft received information about the vulnerability through coordinated vulnerability disclosure. When this security bulletin was issued, Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers.
Mitigating Factors
Microsoft has not identified any mitigating factors for this vulnerability.
Workarounds
Microsoft has not identified any workarounds for this vulnerability.
Microsoft Office Memory Corruption Vulnerability - CVE-2015-0086
A remote code execution vulnerability exists in Microsoft Office software when the Office software fails to properly handle rich text format files in memory.
An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. The file could then, for example, take actions on the behalf of the logged-on user with the same permissions as the current user.
Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. Note that the Preview Pane is an attack vector for this vulnerability. In a web-based attack scenario an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to visit it, typically by getting them to click a link in an instant messenger or email message, and then convince them to open the specially crafted file.
The security update addresses the vulnerability by correcting how Office handles files in memory.

A remote code execution vulnerability exists in Microsoft Office software that is caused when the Office software improperly handles objects in memory while parsing specially crafted Office files. This could corrupt system memory in such a way as to allow an attacker to execute arbitrary code.
An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. The file could then, for example, take actions on the behalf of the logged-on user with the same permissions as the current user.
Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. Note that the Preview Pane is not an attack vector for this vulnerability. In a web-based attack scenario an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to visit it, typically by getting them to click a link in an instant messenger or email message, and then convince them to open the specially crafted file.
The security update addresses the vulnerability by correcting how Microsoft Office parses specially crafted files.
Microsoft received information about the vulnerability through coordinated vulnerability disclosure. When this security bulletin was issued, Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers.

Workarounds
The following workarounds may be helpful in your situation:
Set up a Registry entry to prevent the ADODB.RecordSet ActiveX control from being run in Internet Explorer Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.
Open Registry Editor.
Locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility
On the Edit menu, click New, and then click Key.
Enter the following value:
{00000535-0000-0010-8000-00AA006D2EA4}Select the new key and on the Edit menu, click New, and then click DWORD.
Type CompatibilityFlags, and then press Enter.
On the Edit menu, click Modify and select DWORD (32-bit) Value.
In the Value data box, type 0x00000400, and then click OK.
Exit Registry Editor.
Restart the system.
Impact of workaround: Websites that use the ADODB.RecordSet ActiveX control may no longer display or function correctly in Internet Explorer.
How to undo the workaround.
Open Registry Editor.
Locate and then click the following registry sub key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{00000535-0000-0010-8000-00AA006D2EA4}On the Edit menu, click Delete.
Click Yes when prompted.
Exit Registry Editor.
Restart the system.
Multiple SharePoint XSS Vulnerabilities
Elevation of privilege vulnerabilities exist when SharePoint Server does not properly sanitize a specially crafted request to an affected SharePoint server. An authenticated attacker could exploit these vulnerabilities by sending a specially crafted request to an affected SharePoint server. The attacker who successfully exploited these vulnerabilities could then perform cross-site scripting attacks on affected systems and run script in the security context of the current user.These attacks could allow the attacker to read content that the attacker is not authorized to read, use the victim's identity to take actions on the SharePoint site on behalf of the victim, such as change permissions and delete content, and inject malicious content in the browser of the victim.
The security update addresses the vulnerabilities by helping to ensure that SharePoint Server properly sanitizes user input.
