DSA-771-1 pdns -- varias vulnerabilidades

Fecha del informe:

1 de ago de 2005

Paquetes afectados:

Vulnerable:

Sí

Referencias a bases de datos de seguridad:

En el sistema de seguimiento de errores de Debian: error 318798.
En el diccionario CVE de Mitre: CVE-2005-2301, CVE-2005-2302.

Información adicional:

Se han descubierto varios problemas en pdns, un servidor de nombres versátil, que podían producir una denegación de servicio. El proyecto Common Vulnerabilities and Exposures identifica los siguientes problemas:

CAN-2005-2301
Norbert Sendetzky y Jan de Groot descubrieron que la dorsal de LDAP no saneaba adecuadamente todas las consultas, lo que hacía posible que fallase y que no volviese a responder a ninguna consulta.
CAN-2005-2302
Wilco Baan descubrió que las consultas de los clientes sin permisos para recursividad podían borrar dominios a clientes con permisos para recursividad. Esto permitía que los usuarios externos pudiesen eliminar temporalmente dominios a los usuarios normales.

La distribución estable anterior (woody) no contiene el paquete pdns.

Para la distribución estable (sarge), estos problemas se han corregido en la versión 2.9.17-13sarge1.

Para la distribución inestable (sid), estos problemas se han corregido en la versión 2.9.18-1.

Le recomendamos que actualice el paquete pdns.

Arreglado en:

Debian GNU/Linux 3.1 (sarge)
