This issue was patched in RHSA-2016:2750.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rh-php56-php-mbstring package and not the rh-php56-php-mbstring package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
