Descriptions

Microsoft Office Excel 2007 SP1 and SP2; Office 2008 for Mac; Open XML File Format Converter for Mac; Office Excel Viewer SP1 and SP2; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP1 and SP2; and Office SharePoint Server 2007 SP1 and SP2 do not validate ZIP headers during decompression of Open XML (.XLSX) documents, which allows remote attackers to execute arbitrary code via a crafted document that triggers access to uninitialized memory locations, aka "Microsoft Office Excel XLSX File Parsing Code Execution Vulnerability."

Microsoft Office Excel 2007 SP1 y SP2; Office 2008 para Mac; Open XML File Format Converter para Mac; Office Excel Viewer SP1 y SP2; Office Compatibility Pack para Word, Excel, y PowerPoint 2007 File Formats SP1 y SP2; y Office SharePoint Server 2007 SP1 y SP2 no validan las cabeceras ZIP durante la descompresión de documentos Open XML (.XLSX), lo que permite a atacantes remotos ejecutar código de su elección a través de un documentos manipulado que provoca el acceso a una ubicación de memoria sin inicializar. También conocida como "Vulnerabilidad Microsoft Office Excel XLSX File Parsing Code Execution".

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 file.
The specific flaw exists in the decompression of XLSX files. The XLSX file is a ZIP archive of the associated content making up the new Open XML Document. Due to the lack of validation on the ZIP header when decompressing certain XML elements it is possible to execute uninitialized memory. Successful exploitation can lead to remote code execution under the credentials of the currently logged in user.
