I. Introduction
Open SSL-based heartbleed vulnerability is considered a serious problem of CVE-2014-0160, OpenSSL is widely used in SSL and TLS plug-ins. This article explains how the heartbleed
The impact of the HeartBleed vulnerability on Heartbleed continues to expand. People thought last week that HeartBleed was only a nightmare for web servers, but over time, the threat of Heartbleed to enterprise intranet and data security is truly exposed, resulting in greate
information. The affected computer may be cheated and sent to the server memory.
Who found this problem?
This vulnerability was independently discovered by Codenomicon and Google security researchers. To minimize the impact, the researchers have already worked with the OpenSSL team and other key insiders to prepare a solution before releasing the issue.

According to the Re/code website, the Heartbleed vulnerability that shocked the entire Internet world last week has aroused panic. However, the latest report shows that most websites have been updated to fix this vulnerability. Internet Security Company Sucuri conducted a systematic scan of 1 million websites. The results showed that most of the top 1000 websites

The high-risk OpenSSL vulnerability Heartbleed published in April 7 has become the leading news of IT security for two consecutive weeks. Now IT experts are arguing about the impact of the vulnerability and the cost of fixing the vulnerability: To fix the vulnerability, many
This article is published by Tom Simonite on the TechnologyReview website in the article titled "connecting Devices Will Never Be Patched to Fix the Heartbleed Bug, this article describes the OpenSSL vulnerability and mentions that many online devices may never be able to fix this vulnerability because of the lack of necessary security management and software upd
From Finland to Silicon Valley, a small team of vulnerability hunters found the most serious network security vulnerability in the history of the Internet and actively prepared for it.
Recently, Heartbleed is a widely used word. This security vulnerability has aroused the worries of almost every Internet user. But as e
Search OpenSSL Heartbleed on the Internet to view tens of thousands of related content. Not only is online banking affected, but many security links encrypted through OpenSSL have certain risks. Therefore, it is best to upgrade all its OpenSSL as soon as possible.For example, the OpenSSL version of The RedHat system is 0.9.8, and non-registered users cannot automatically upgrade to the latest version 1.0.1g through yum.However, we can use the source c
The Heartbleed problem is actually worse than it can be seen now (it seems to be broken now ). Heartbleed (CVE-2014-0160) is an OpenSSL vulnerability that allows any remote user to dump some of the server's memory. Yes, it's really bad. It is worth noting that a skilled user can use it to dump the RSA private key used by the server to communicate with the custome
