Descriptions

PowerDNS Recursor before 3.1.5 uses insufficient randomness to calculate (1) TRXID values and (2) UDP source port numbers, which makes it easier for remote attackers to poison a DNS cache, related to (a) algorithmic deficiencies in rand and random functions in external libraries, (b) use of a 32-bit seed value, and (c) choice of the time of day as the sole seeding information.

PowerDNS Recursor anterior a 3.1.5 no emplea la suficiente aleatoriedad para calcular (1) los valores TRXID y (2) números de las fuentes de los puertos UDP; esto hace que sea más fácil a los atacantes remotos envenenar una caché de DNS relacionada con (a) deficiencias algorítmicas en las funciones rand y random de librerias externas, (b) uso de una semilla de 32-bit, y (3) elección del momento del día como la única semilla de información.
