CVE-2015-8867 (opens in a new tab)How to fix?
Upgrade RHEL:7 rh-php56-php-cli to version 0:5.6.25-1.el7 or higher.
This issue was patched in RHSA-2016:2750.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rh-php56-php-cli package and not the rh-php56-php-cli 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.
