Microsoft Security Bulletin MS12-014 - Important
Vulnerability in Indeo Codec Could Allow Remote Code Execution (2661637)

Published: Tuesday, February 14, 2012 | Updated: Wednesday, February 22, 2012

Version: 1.1
General Information
Executive Summary

This security update resolves one publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a legitimate file (such as an .avi file) that is located in the same directory as a specially crafted dynamic link library (DLL) file. An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. 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 Important for Windows XP Service Pack 3. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerability by correcting the manner in which the Indeo Codec loads external libraries. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
