Descriptions

The Linear Congruential Generator (LCG) in PHP before 5.2.13 does not provide the expected entropy, which makes it easier for context-dependent attackers to guess values that were intended to be unpredictable, as demonstrated by session cookies generated by using the uniqid function.

El Linear Congruential Generator (LCG) en PHP anteriores a v5.2.13 no provee la entropía esperada, lo que hace más fácil para atacantes dependiendo del contexto adivinar valores que deberían ser impredecibles, como se demostró con cookies de sesión generadas utilizando la función uniqid.
