Description |
|
|
Se ha encontrado una vulnerabilidad de tipo desbordamiento de búfer en la librería libxslt 1.1.23 y anteriores. La vulnerabilidad reside en un error en la comprobación de los límites durante la transformación XML de un documento en el fichero "pattern.c". Un atacante remoto podría causar una denegación de servicio y posiblemente ejecutar código arbitrario mediante un fichero de hoja de estilo XSL especialmente diseñado con una condición XSLT larga. Existe una prueba de concepto disponible. |
