Status of different versions: OpenSSL 1.0.1 through 1.0.1f (inclusive) are vulnerable OpenSSL 1.0.1g is NOT vulnerable OpenSSL 1.0.0 branch is NOT vulnerable OpenSSL 0.9.8 branch is NOT vulnerable Bug was introduced to OpenSSL in December 2011 and has been out in the wild since OpenSSL release 1.0.1 on 14th of March 2012.

Help for Remote detection of vulnerable OpenSSL versions It is difficult to tell OpenSSL 0.9.6e from vulnerable versions because the OpenSSL developers chose to terminate the process if a buffer overflow attempt is detected. Over the network, a crash due to a buffer overflow and an abrupt, but deliberate process termination look the same: in both cases, the TCP connection breaks down. At first glance Multiple Vulnerabilities in OpenSSL Affecting Cisco Sep 27, 2016 How to Fix Heartbleed Vulnerability? | ClickSSL The bug compromised the keys used on a host with OpenSSL vulnerable versions. To fix Heartbleed bug, users have to update their older OpenSSL versions and revoke any previous keys. We will here present a procedure to update the system with a secure OpenSSL versions. Step: 1. Update OpenSSL version. For Ubuntu and Debian system update:

OpenSSL

NVD - Results Any OpenSSL internal use of this cipher, including in SSL/TLS, is safe because no such use sets such a long nonce value. However user applications that use this cipher directly and set a non-default nonce length to be longer than 12 bytes may be vulnerable. OpenSSL versions …

Heartbleed is a security bug in the OpenSSL cryptography library, which is a widely used implementation of the Transport Layer Security (TLS) protocol. It was introduced into the software in 2012 and publicly disclosed in April 2014. Heartbleed may be exploited regardless of whether the vulnerable OpenSSL instance is running as a TLS server or client.

This only affects you if you are running OpenSSL versions 1.0.1 through 1.0.1f and 1.0.2-beta1, or if you are running software that is using affected versions of the OpenSSL library. The steps to secure your environment against the Heartbleed Bug vulnerability must be done in the following order.
