The Execute()
function of the ADODB.Connection ActiveX object contains an unspecified vulnerability. This may allow a remote, unauthenticated attacker to cause Internet Explorer to crash or possibly execute arbitrary code.
Microsoft ADO (ActiveX Data Objects) are “… language-neutral object model that expose data raised by an underlying OLE DB Provider.” 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.
By 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.
Apply an update
This issue is addressed in Microsoft Security Bulletin MS07-009. This Bulletin provides updated versions of MDAC, which include updated ADODB ActiveX controls.
Disable the ADODB.Connection ActiveX control in Internet Explorer
The ADODB.Connection ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSID:
{00000514-0000-0010-8000-00AA006D2EA4}
More information about how to set the kill bit is available in Microsoft Support Document 240797.
Disable ActiveX
Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this vulnerability. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document and the Malicious Web Scripts FAQ.
