Who is Vulnerable?
Vulnerability Description Microsoft Excel is a popular spreadsheet application that is usually released as part of the Microsoft Office suite. The application can create complex spreadsheets with multiple workbooks, formulae, and various data sources. The proprietary file format used for storing Microsoft Excel documents is known as the Binary Interchange File Format (BIFF), with different versions of the application supporting different versions of the format. The common extension used for Microsoft Excel documents is .xls. There exists a memory corruption vulnerability in Microsoft Excel. The flaw is caused by an insufficient checks while parsing the Column field in several record types in Excel files. A remote attacker can exploit this vulnerability by enticing the target user to open a crafted Excel file, potentially causing arbitrary code to be injected and executed in the security context of the current user. In case of an attack where code injection is not successful, all instances of the vulnerable application will terminate or the application will stop responding. This can lead to a loss of data. In case of an attack where code injection and execution 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.
