CVE-2015-8867 (opens in a new tab)How to fix?
Upgrade Debian:8 php5 to version 5.6.12+dfsg-0+deb8u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php5 package and not the php5 package as distributed by Debian.
See How to fix? for Debian:8 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.
