Descripción |
|
|
Se ha encontrado una vulnerabilidad del tipo desbordamiento de búfer en OpenBSD de la versión 4.0 hasta la 4.2 en dhcpd y en algunas implementaciones de éste basadas en ISC dhcp-2. La vulnerabilidad reside en un error en el archivo options.c en la función cons_options. Un atacante remoto podría ejecutar código arbitrario o causar una denegación de servicio mediante una petición DHCP especificando el tamaño máximo de mensaje más pequeño que el tamaño mínimo para la MTU. |
