Version: 1.0

 

Summary

 

Who should read this document: Customers who use Microsoft Windows

Impact of Vulnerability: Remote Code Execution

Maximum Severity Rating: Critical

Recommendation: Customers should apply the update immediately.

Security Update Replacement: This update replaces the update that is included with Microsoft Security Bulletin MS05-052. That update is also a cumulative update.

 

Vulnerability Details:

A remote code execution vulnerability exists in the way Internet Explorer displays file download dialog boxes and accepts user input during interaction with a Web page. This interaction could be in the form of certain keystrokes that a user makes when visiting a Web page. A custom dialog box may also be positioned in front of a file download dialog box to make this more convincing. A user may also be persuaded to double-click an element of a Web page.

 

An attacker could exploit the vulnerability by constructing a malicious Web page that could potentially allow remote code execution if a user visited the malicious Web site. An attacker who successfully exploited this vulnerability could take complete control of an affected system. However, significant user interaction is required to exploit this vulnerability.
