Soporte de vulnerabilidades

Servicio de soporte de vulnerabilidadesAnálisis, notificación y seguimiento de aquellas vulnerabilidades más críticas, que impactan especialmente en las tecnologías empleadas en el sector público. El CCN-CERT trabajará en la recopilación y clasificación de las nuevas vulnerabilidades, realizando un análisis teórico y en laboratorio, cuando sea posible, de aquellas que por su criticidad lo requieran.

Se generarán documentos informativos o “abstracts” de dichas vulnerabilidades y se llevará a cabo un seguimiento de la evolución de la vulnerabilidad en Internet, alertando a los organismos ante cambios en la criticidad, aparición de parches, nuevas recomendaciones, constancia de explotaciones activas, etc.

Para inscribirse en este servicio o recibir más información, escribir al correo electrónico: soporte_acreditacion@ccn.cni.es

Descripción

Se han descubierto múltiples vulnerabilidades en las versiones anteriores a la 2.9.18 del servidor de nombres PowerDNS. Las vulnerabilidades son descritas a continuación:

- CAN-2005-2301: Vulnerabilidad en el manejo de peticiones LDAP podría permitir a un atacante remoto provocar una situación de denegación de servicio o incluso inyectar entradas LDAP.

- CAN-2005-2302: Vulnerabilidad en el manejo de peticiones desde clientes sin recursividad permitida podría perjudicar a los clientes con recursividad permitida.

Solución

Si lo desea, aplique los mecanismos de actualización propios de su distribución, o bien baje las fuentes del software y compílelo usted mismo.
