Microsoft Security Bulletin MS12-045 - Critical
Vulnerability in Microsoft Data Access Components Could Allow Remote Code Execution (2698365)
Published: Tuesday, July 10, 2012 | Updated: Tuesday, September 11, 2012
Version: 1.3
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user views a specially crafted webpage. 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 all supported editions of Windows XP, Windows Vista, and Windows 7; and Moderate 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.
The security update addresses the vulnerability by changing the way that Microsoft Data Access Components handles objects in memory. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Recommendation. The majority of customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically.
