Referencias a bases de datos de seguridad:

En el diccionario CVE de Mitre: CVE-2003-0026.
Notas y avisos de incidentes y vulnerabilidades en CERT: VU#284857, CA-2003-01.

Información adicional:

El Consorcio de Software de Internet (ISC) descubrió varias vulnerabilidades durante una auditoría del demonio DHCP de ISC. Las vulnerabilidades existían en las rutinas de gestión de error de la biblioteca minires y se podían explotar por desbordamientos de pila. Esto podía permitir a un atacante remoto ejecutar código arbitrario bajo el id del usuario bajo el corriera dhcpd, normalmente root. Otros servidores DHCP distintos a dhcp3 no parecen verse afectados.

Para la distribución estable (woody), este problema se ha corregido en la versión 3.0+3.0.1rc9-2.1.

La distribución estable anterior (potato) no tenía los paquetes de dhcp3.

Para la distribución inestable (sid), este problema se ha corregido en la versión 3.0+3.0.1rc11-1.

Le recomendamos que actualice el paquete dhcp3-server.

Arreglado en:

Debian GNU/Linux 3.0 (woody)
