OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites. Sep 12, 2019 · 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 . This article will provide IT teams with the necessary information to decide whether or not to apply the Heartbleed vulnerability fix. The Heartbleed Bug is an OpenSSL vulnerability that would allow malicious hackers to steal information from websites that would normally be protected by the SSL/TLS encryption. The open source OpenSSL cryptography library is used to implement the Internet's Transport Layer Security (TLS) protocol.
