CVE-2016-1902

The nextBytes function in the SecureRandom class in Symfony before 2.3.37, 2.6.x before 2.6.13, and 2.7.x before 2.7.9 does not properly generate random numbers when used with PHP 5.x without the paragonie/random_compat library and the openssl_random_pseudo_bytes function fails, which makes it easier for attackers to defeat cryptographic protection mechanisms via unspecified vectors.

La función nextBytes en la clase SecureRandom en Symfony en versiones anteriores a 2.3.37, 2.6.x en versiones anteriores a 2.6.13 y 2.7.x en versiones anteriores a 2.7.9 no genera correctamente números aleatorios cuando es usado con PHP 5.x sin la biblioteca paragonie/random_compat y falla la función openssl_random_pseudo_bytes, lo que hace más fácil a los atacantes vencer los mecanismos de protección de cifrado a través de vectores no especificados.
