PHP Cryptographic Issues Vulnerability - CVE-2015-8867
The openssl_random_pseudo_bytes function in ext/openssl/openssl.c in PHP before 5.4.44 5.5.x before 5.5.28 and 5.6.x before 5.6.12 incorrectly relies on the deprecated RAND_pseudo_bytes function which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors.
