What is the Heartbleed bug, how does it work and how was

First we explained how it worked, and now, thanks to Jared Stafford (and stbnps on Github for explanations) we can show you how to exploit it. Heartbleed is a simple bug, and therefore a simple bug to exploit. As you'll see below, it only takes about a single page of Python to exploit this bug. Doubtless, the Heartbleed bug (CVE-2014-0160) that was discovered by Matti, Antti, Riku (from Codenomicon) and Neel Metha (from Google) is devastading vulnerability in the OpenSSL library that make possible any attacker to steal tons of protected information from a system that’s using a The Heartbleed flaw in OpenSSL. The fatal flaw (that has been named Heartbleed) is that the OpenSSL library never checked that the Heartbeat payload size corresponds with the actual length of the payload being sent. A user is allowed to input any number up to 65535 (64 kilobytes) regardless of the true size of the payload. Apr 08, 2014 · The bug itself is called "Heartbleed" because it occurs in the heartbeat extension. Codenomicon explained that the bug is in the OpenSSL's implementation of the TLS/DTLS (transport layer security protocols) heartbeat extension (RFC6520). "When it is exploited it leads to the leak of memory contents from the server to the client and from the

In a post to the Errata Security blog, Robert Graham explained that it is highly unlikely that private key data would be stored in the memory buffer that could be leaked using the Heartbleed
