Who is Vulnerable?
Vulnerability Description There exists an arbitrary index pointer code execution vulnerability in Microsoft Excel. The flaw is caused by an insufficient check of a malformed OBJECT Record in an Excel file. An attacker can exploit this vulnerability to inject and execute arbitrary code in the security context of the currently logged in user. In an attack case where code injection is not successful, the Microsoft Excel application will terminate. This can potentially lead to a loss of data. In a more sophisticated attack where code injection is successful, the behavior of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user.
