CVE-2014-0160 - Heartbleed. Late Monday, April 7th, 2014, a bug was disclosed in OpenSSL's implementation of the TLS heartbeat extension. The bug's official designation is CVE-2014-0160, it has also been dubbed Heartbleed in reference to the heartbeat extension it affects.

The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. Heartbleed was caused by a flaw in OpenSSL, an open source code library that implemented the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. In short, a malicious user OpenSSL versions 1.0.1 through 1.0.1f contain a flaw in its implementation of the TLS/DTLS heartbeat functionality. This flaw allows an attacker to retrieve private memory of an application that uses the vulnerable OpenSSL library in chunks of 64k at a time. CVE-2014-0160 - Heartbleed.

Heartbleed Bug: Flaw in OpenSSL versions 1.0.1 through 1.0.1f and 1.0.2-beta1. On April 7, 2014, the Heartbleed bug was revealed to the Internet community. The Heartbleed bug is not a flaw in the SSL or TLS protocols; rather, it is a flaw in the OpenSSL implementation of the TLS/DTLS heartbeat functionality. Heartbleed is a play on words referring to an extension on OpenSSL called "heartbeat." The protocol is used to keep connections open, even when data isn't being shared between those connections.

In this time, we all are aware about the new Open SSL Heartbleed vulnerability. The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. You will get more details from this link Heartbleed. Is your website affected with the HeartBleed SSL Bug Mar 28, 2019 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

The vulnerability occurs due * to bounds checking not being performed on a heap value which * is user supplied and returned to the user as part of DTLS/TLS * heartbeat SSL extension. All versions of OpenSSL 1.0.1 to * 1.0.1f are known affected. You must run this against a target * which is linked to a vulnerable OpenSSL library using DTLS/TLS.
