Microsoft Windows may allow remote code execution through specially crafted OLE2 documents.
Microsoft object linking and embedding (OLE) is a technology that allows applications to create and edit compound documents. Compound documents can contain embedded documents or links to documents with different formats. Microsoft Word and Excel are examples of programs that use OLE compound documents. OLE2 is version 2 of the OLE architecture.
If an OLE2 document has an unrecognized file extension, the Windows Shell/Windows Explorer may determine which application should be used to open it by inspecting the class identifier (ClassID) within the document. This design may cause unpredictable and potentially damaging behavior if an attacker crafts an OLE2 document with a ClassID that references an arbitrary application.
By persuading a user to view a specially crafted OLE2 document, an attacker could execute arbitrary code with the privileges of the user.
