Sneak Peek –The Heartbleed Bug!!
The Heartbleed Bug
The Heartbleed Bug is a critical vulnerability in the mainstream OpenSSL cryptographic programming library. This permits stealing data like passwords credit card no. etc. which is secured, under ordinary conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS gives security and protection over the Internet for requisitions, for example, web, email, texting( (IM) and some virtual private networking systems (VPNS).
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. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).
The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
What is the CVE-2014-0160?
CVE-2014-0160 is the official reference to this bug. CVE (Common Vulnerabilities and Exposures) is the Standard for Information Security Vulnerability Names maintained by MITRE. Due to co-incident discovery a duplicate CVE, CVE-2014-0346, which was assigned to us, should not be used, since others independently went public with the CVE-2014-0160 identifier.
Why it is called the Heartbleed Bug?
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 client to the server.
