Description |
|
|
Se ha encontrado una vulnerabilidad de tipo desbordamiento de pila en Mtr en versiones anteriores a la 0.73. La vulnerabilidad reside en un error en la comprobación de los límites en la función "split_redraw()" del fichero "split.c" cuando se inicia con la opción "-p". Un atacante remoto con control del servidor DNS que utiliza la víctima podría ejecutar código arbitrario mediante un "DNS PTR" especialmente diseñado. |
