If el6_0 to el6_5.4 were vulnerable, and the fix is el6_5.7, what of the missing versions el6_5.5 and el6_5.6? Did it take three patches to finally fix this, or was it noticed and fixed earlier? Duane, you can get part of your answer by running the following command …

OpenSSL Heartbeat 'Heartbleed' Vulnerability Apr 18, 2014 Heartbleed encryption flaw leaves millions of sites at Apr 09, 2014

Five years later, Heartbleed vulnerability still unpatched

Why is this version of OpenSSL (1.0.1e) not vulnerable to From what I know, versions between 1.0.1 through to 1.0.1f are vulnerable. I can see that it was built on a later date. My questions are: Which compile option made it safe against Heartbleed? I don't see DOPENSSL_NO_HEARTBEATS flag option in the output above.

Security Advisory Relating to OpenSSL Vulnerability

The Heartbleed bug is a vulnerability in a popular open-source implementation of the SSL/TLS protocol, called OpenSSL. It may allow unauthenticated remote attackers on the Internet to read the memory of connected systems which use vulnerable versions of the OpenSSL library, which may compromise high value assets such as secret keys used to Heartbleed Bug Impacts Online Retailers, Ecommerce Apr 10, 2014 New MitM Vulnerability Plagues Client, Server Versions of “The attack can only be performed between a vulnerable client and server. OpenSSL clients are vulnerable in all versions of OpenSSL. Servers are only known to be vulnerable in OpenSSL 1.0.1 and 1.0.2-beta1. Users of OpenSSL servers earlier than 1.0.1 are advised to upgrade as a precaution,” the OpenSSL Project noted in its advisory. Detection and Exploitation of OpenSSL Heartbleed In this article we will discuss how to detect and exploit systems that are vulnerable to the OpenSSL-Heartbleed vulnerability using Nmap and Metasploit on Kali Linux. Around 200000+ servers are still vulnerable to Heartbleed which is a serious vulnerability in the most popular OpenSSL cryptographic software library. Through this vulnerability, an attacker can easily steal […]
