Descriptions

The arc4random function in the kernel in FreeBSD 6.3 through 7.1 does not have a proper entropy source for a short time period immediately after boot, which makes it easier for attackers to predict the function's return values and conduct certain attacks against the GEOM framework and various network protocols, related to the Yarrow random number generator.

La función arc4random en el kernel enFreeBSD 6.3 a 7.1 no tiene una adecuada fuente de entropía durante un corto período de tiempo inmediatamente después del arranque, lo cual hace más fácil para los atacantes predecir los valores de retorno de la función y llevar a cabo ciertos ataques contra el GEOM framework y diversos protocolos de red en relación con el generador de números aleatorios Yarrow.
