Office Excel 2002 SP3, 2003 SP3 y 2007 SP1 y SP2; Office 2004 y 2008 para Mac; Open XML File Format Converter para Mac; Office Excel Viewer 2003 SP3; Office Excel Viewer SP1 y SP2; y Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP1 y SP2, de Microsoft, permite a los atacantes remotos ejecutar código arbitrario por medio de una hoja de cálculo con un registro FEATHEADER que contiene un elemento de tamaño cbHdrData no válido que afecta a un desplazamiento del puntero, también se conoce como "Excel Featheader Record Memory Corruption Vulnerability".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office Excel. User interaction is required to exploit this vulnerability in that the target must open a malicious spreadsheet.
The specific flaw exists in the handling of Shared Feature Header (0x867) tags in an Excel BIFF file format. When processing the cbHdrData size element of the FEATHEADER it is possible to directly control the distance of a calculated pointer. This condition can be leveraged successfully to execute arbitrary code under the context of the currently logged in user.

Microsoft Office Excel allows remote attackers to execute arbitrary code via a spreadsheet with a FEATHEADER record containing an invalid cbHdrData size element that affects a pointer offset.
