Description |
|
|
Se ha descubierto una vulnerabilidad de desbordamiento de búfer en las versiones 0.7.4, 0.7.5, 0.7.6 y 1.0.0 de la librería wvWare utilizada para cargar y parsear documentos en formato Microsoft Word en sistemas Unix. La vulnerabilidad reside en el manejo del campo 'DateTime' por parte de la función wvHandleDateTimePicture(). La explotación de esta vulnerabilidad podría permitir a un atacante remoto ejecutar código mediante un documento especialmente diseñado que la víctima debe abrir con algún software que haga uso de librería wvWare. |
