FKIE_CVE-2015-8867
Vulnerability from fkie_nvd - Published: 2016-05-22 01:59 - Updated: 2026-06-17 00:35
Severity
Summary
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.
