What is the Heartbleed virus
Heartbleed was a vulnerability in some implementations of OpenSSL, an open source cryptographic library. It was publicly announced by researchers on April 7, 2014 and patched the same month.
Is Heartbleed still a problem
Through a validation process, the researcher found that Shodan was mostly correct in its assessments. Clearly, while mitigation is available, Heartbleed is still a problem. If you're using TuxCare's library patching service, LibraryCare, you have little to worry about, as your libraries will always be up to date.
How bad was Heartbleed
It's not just a server-side vulnerability, it's also a client-side vulnerability because the server, or whomever you connect to, is as able to ask you for a heartbeat back as you are to ask them. The stolen data could contain usernames and passwords. Reverse Heartbleed affected millions of application instances.
What is the cause of Heartbleed
The Heartbleed vulnerability arose because OpenSSL's implementation of the heartbeat functionality was missing a crucial safeguard: the computer that received the heartbeat request never checked to make sure the request was actually as long as it claimed to be.
Who found the heartbleed bug
Codenomicon first discovered Heartbleed—originally known by the infinitely less catchy name “CVE-2014-0160”—during a routine test of its software.
What is the mistake in the heartbleed bug code
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.
How was the Heartbleed bug fixed
The Heartbleed fix
Bodo Moeller and Adam Langley of Google created the fix for Heartbleed. They wrote a code that told the Heartbeat extension to ignore any Heartbeat Request message that asks for more data than the payload needs.
Who is responsible for the heartbleed bug
Robin Seggelmann, a programmer based in Germany, submitted the code in an update submitted at 11:59pm on New Year's Eve, 2011. It was supposed to enable a function called "Heartbeat" in OpenSSL, the software package used by nearly half of all web servers to enable secure connections.

How do you solve Heartbleed vulnerability
Change your password on every site that you use, after you have verified that they have updated their OpenSSL versions to patch this vulnerability. If you change your password prior to the remote site patching their SSL version, your new password is just as vulnerable as your old one.
How was Heartbleed patched

When did the Heartbleed Bug come out
The Heartbleed vulnerability was introduced into the OpenSSL crypto library in 2012. It was discovered and fixed in 2014, yet today—five years later—there are still unpatched systems.
Could the Heartbleed have been avoided
The problem could have been avoided by validating the message length and ignoring Heartbeat request messages asking for more data than their payload needs.

What is the heartbeat bug 2014
The Heartbleed bug is a vulnerability in open source software that was first discovered in 2014. Anyone with an internet connection can exploit this bug to read the memory of vulnerable systems, leaving no evidence of a compromised system.

What is the CVE 2014 0160
Description. An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server.
What does CVE 2014 6271 belong to
The Shellshock Vulnerability (CVE-2014-6271) is a serious vulnerability in Bash on Linux. According to RedHat, “A flaw was found in the way Bash (aka bourne-again shell) evaluated certain specially crafted environment variables.
How did Heartbleed work
OpenSSL processes in the machine that are responding to Heartbeat requests don't verify if the payload size is same as what is specified in length field. Thus, the machine copies extra data residing in memory after the payload into the response. This is how the Heartbleed vulnerability works.
