CVE-2016-0704  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade Centos:6 openssl-perl to version 0:1.0.1e-30.el6_6.7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl-perl package and not the openssl-perl package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

An oracle protection mechanism in the get_client_master_key function in s2_srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a overwrites incorrect MASTER-KEY bytes during use of export cipher suites, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, a related issue to CVE-2016-0800.
