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.
