Microsoft Security Bulletin MS11-002 - Critical
Vulnerabilities in Microsoft Data Access Components Could Allow Remote Code
Execution (2451910)
Published: January 11, 2011
Version: 1.0
General Information
Executive Summary
This security update resolves two privately reported vulnerabilities
in Microsoft Data Access Components. The vulnerabilities could allow
remote code execution if a user views a specially crafted Web page. An
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.
This security update is rated Critical for all supported editions of
Windows XP, Windows Vista, and Windows 7, and Important for all
supported editions of Windows Server 2003, Windows Server 2008, and
Windows Server 2008 R2. For more information, see the subsection,
Affected and Non-Affected Software, in this section.

Vulnerability Information
DSN Overflow Vulnerability - CVE-2011-0026
A remote code execution vulnerability exists in the way that Microsoft
Data Access Components validates third-party API usage. This
vulnerability could allow code execution if a user visited a specially
crafted Web page. 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. 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.
ADO Record Memory Vulnerability - CVE-2011-0027
A remote code execution vulnerability exists in the way that Microsoft
Data Access Components validates memory allocation. This vulnerability
could allow code execution if a user visited a specially crafted Web
page. 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. 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.
