Microsoft Security Bulletin MS10-044 - Critical
Vulnerabilities in Microsoft Office Access ActiveX Controls Could Allow
Remote Code Execution (982335)
Version: 1.0
General Information
Executive Summary
This security update resolves two privately reported vulnerabilities
in Microsoft Office Access ActiveX Controls. The vulnerabilities could
allow remote code execution if a user opened a specially crafted
Office file or viewed a Web page that instantiated Access ActiveX
controls. 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 supported editions of
Microsoft Office Access 2003 and Microsoft Office Access 2007. For
more information, see the subsection, Affected and Non-Affected
Software, in this section.
The update addresses the vulnerabilities by updating specific Access
ActiveX controls and by modifying the way memory is accessed by
Microsoft Office and by Internet Explorer when loading Access ActiveX
controls. For more information about the vulnerability, see the
Frequently Asked Questions (FAQ) subsection for the specific
vulnerability entry under the next section, Vulnerability Information.
Affected Software
Microsoft Office Access 2003 Service Pack 3
Microsoft Office Access 2007 Service Pack 1
Microsoft Office Access 2007 Service Pack 2
Vulnerability Information
Access ActiveX Control Vulnerability- CVE-2010-0814
A remote code execution vulnerability exists in Access ActiveX
controls due to the way that multiple ActiveX controls are loaded by
Internet Explorer. An attacker who successfully exploited this
vulnerability could run arbitrary code as the logged-on user. If a
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.
ACCWIZ.dll Uninitialized Variable Vulnerability - CVE-2010-1881
A remote code execution vulnerability exists in the way that the
FieldList ActiveX control is instantiated by Microsoft Office and
Internet Explorer. An attacker who successfully exploited this
vulnerability could run arbitrary code as the logged-on user. If a
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.
