Insecure Random Number Generation in Symfony's SecureRandom Class

Insecure Random Number Generation in Symfony's SecureRandom Class

CVE-2016-1902 · MEDIUM Severity

AV:N/AC:L/AU:N/C:P/I:N/A:N

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.
