Descriptions

The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5, when running on 64-bit systems, performs a multiplication that generates a portion of zero bits during conversion due to insufficient precision, which produces 24 bits of entropy and simplifies brute force attacks against protection mechanisms that use the rand and mt_rand functions.

La macro GENERATE_SEED de PHP 4.x versiones anteriores a la 4.4.8 y 5.x versiones anteriores a la 5.2.5, cuando se ejecuta en sistemas de 64 bits, realiza un producto que genera una porción de bits cero durante la conversión debido a la falta de precisión, lo que provoca 24 bits de entropía y simplifican los ataques por fuerza bruta contra mecanismos de protección que utilizan la secuencia generada y las funciones mt-rand.
