CVE-2016-1902: Cryptographic Issues

June 1, 2016 (updated June 3, 2016)

The nextBytes function in the SecureRandom class does not properly generate random numbers when used with PHP 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.
