Descriptions

MaraDNS 1.3.07.12 and 1.4.08 computes hash values for DNS data without properly restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted queries with the Recursion Desired (RD) bit set. NOTE: this issue exists because of an incomplete fix for CVE-2012-0024.

MaraDNS v1.3.07.12 y v1.4.08 calcula los valores hash de los datos DNS sin restringir la capacidad de desencadenar colisiones hash de forma predecible, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de CPU) mediante el envío de muchas consultas a mano con el bit Recursion Desired (recursividad deseada - RD) activado. NOTA: este problema existe debido a una solución incompleta para CVE-2012-0024.
