How was the Heartbleed bug fixed?

Following the discovery of the vulnerability, Google employees found a solution and provided OpenSSL contributors with the code that fixed the issue. OpenSSL users were then instructed to upgrade to the latest OpenSSL version.

How does Heartbleed vulnerability happen?

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.

What did the Heartbleed bug allow hackers to do?

The bug, which surfaced Monday, allows hackers to steal data without a trace. No organization has identified itself as a victim, yet security firms say they have seen well-known hacking groups scanning the Web in search of vulnerable networks.

What type of vulnerability is Heartbleed?

The Heartbleed Bug. 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.

Why is it called Heartbleed?

The vulnerability, which is more formally known as CVE-2014-0160, allows an attacker to read up to 64 kilobytes of memory per attack on any connected client or server. Heartbleed got its name because it is a flaw in OpenSSL’s implementation of the Heartbeat Extension for the TLS and DTLS protocols (RFC 6520).

Why is Heartbleed called Heartbleed?

Heartbleed got its name because it is a flaw in OpenSSL’s implementation of the Heartbeat Extension for the TLS and DTLS protocols (RFC 6520). The vulnerability, which is caused by poorly-written code, was discovered on the same day by Google and Codenomicon security researchers.

Is Heartbleed a buffer overflow?

The Heartbleed vulnerability is a memory buffer overflow, where if the machine receives less packets than it is expecting to receive, it randomly grabs bits of information from memory to pad out the response to the correct size.

Who is responsible for the heartbleed bug?

Although the OpenSSL Software Foundation has no bug bounty program, the Internet Bug Bounty initiative awarded US$15,000 to Google’s Neel Mehta, who discovered Heartbleed, for his responsible disclosure.
