This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Microsoft Office. Exploitation requires that the attacker coerce the target user into opening a malicious .XLS file. The specific flaw exists during the processing of malformed charts embedded within a Word document. Upon closing the document, certain pointers are corrupted with data direclty from the file. A later dereference of these corrupted pointers can result in code execution.
