The Microsoft XML Core Services XMLHTTP ActiveX control contains an unspecified vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Microsoft XML Core Services (MSXML) allow developers who use applications such as JScript, Visual Basic Scripting Edition (VBScript), and Microsoft Visual Studio to create XML-based applications. MSXML includes the XMLHTTP ActiveX control, which allows web pages to transmit or receive XML data via HTTP operations. MSXML 4.0 does not come with Windows XP by default, but is available as a separate download and is also bundled with many applications.
The XMLHTTP 4.0 ActiveX control contains an unspecified memory corruption vulnerability. When certain methods of the XMLHTTP ActiveX control are called with invalid parameters, process memory is corrupted in an exploitable manner.
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.
