The ADODB.Connection ActiveX control contains a vulnerability that can cause memory corruption in the application that is hosting the control, such as Internet Explorer.II. ImpactBy convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.III. SolutionApply an updateThis issue is addressed in Microsoft Security Bulletin MS07-009. This Bulletin provides updated versions of MDAC, which include updated ADODB ActiveX controls.
