Descriptions

The "internal state tracking" code for the random and urandom devices in FreeBSD 5.5, 6.1 through 6.3, and 7.0 beta 4 allows local users to obtain portions of previously-accessed random values, which could be leveraged to bypass protection mechanisms that rely on secrecy of those values.

El código de "seguimiento del estado interno" para los dispositivos random y urandom de FreeBSD 5.5, 6.1 hasta 6.3, y 7.0 beta 4 permite a usuarios locales obtener parte de valores aleatorios que han sido accedidos previamente, lo cual podría aprovechado para evitar los mecanismos de protección basados en mantener estos valores en secreto.

Under certain circumstances, a bug in the internal state tracking on the random and urandom devices can be exploited to allow replaying of data distributed during subsequent reads.
