Descriptions

Microsoft Excel 2002 SP3, Office 2008 for Mac, and Open XML File Format Converter for Mac do not properly validate record information during parsing of Excel spreadsheets, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted spreadsheet, aka "Excel Memory Corruption Vulnerability."

Microsoft Excel 2002 SP3, Office 2008 para Mac, y el conversor de formato de fichero Open XML para Mac no validan apropiadamente la información de registro durante el análisis (parseo) de hojas de cálculo Excel, lo que permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de una hoja de cálculo modificada. También conocida como "vunerabilidad de corrupción de memoria Excel".
