Descriptions

Apache OpenOffice opens dBase/DBF documents and shows the contents as spreadsheets. DBF are database files with data organized in fields. When reading DBF data the size of certain fields is not checked: the data is just copied into local variables. A carefully crafted document could overflow the allocated space, leading to the execution of arbitrary code by altering the contents of the program stack. This issue affects Apache OpenOffice up to and including version 4.1.10

Apache OpenOffice abre documentos dBase/DBF y muestra el contenido como hojas de cálculo. Los DBF son archivos de bases de datos con datos organizados en campos. Cuando se leen datos DBF no se comprueba el tamaño de ciertos campos: los datos se copian simplemente en variables locales. Un documento cuidadosamente diseñado podría desbordar el espacio asignado, conllevando a una ejecución de código arbitrario al alterar el contenido de la pila del programa. Este problema afecta a Apache OpenOffice hasta la versión 4.1.10, incluyéndola
