Updated

The opensslrandompseudobytes 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 RANDpseudobytes function, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors.
