OLE Object Instantiation Vulnerability in Microsoft Visual Studio and Windows

CVE-2009-2493

What is CVE-2009-2493?

The vulnerability resides in the Active Template Library (ATL), which does not securely restrict the use of OleLoadFromStream. This flaw allows attackers to instantiate objects from potentially malicious data streams, enabling the execution of arbitrary code when users open specially crafted HTML documents that contain these ATL components. Proper security measures and restrictions put in place by the software are bypassed, leading to risks of unauthorized access and control over affected systems.
