The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected by the SSL encryption used to secure the Internet. SSL provides security and privacy for applications such as web, email, instant messaging (IM) and virtual private networks (VPNs).
The Heartbleed bug allows anyone on the Internet to read the user names and passwords, instant messages, emails and business critical documents and communication protected by the vulnerable versions of the OpenSSL software. It compromises the secret keys used to identify the service providers and to encrypt the traffic. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
Operating system distributions that have shipped with the vulnerable OpenSSL version:
Debian Wheezy (stable), OpenSSL 1.0.1e-2+deb7u4
Ubuntu 12.04.4 LTS, OpenSSL 1.0.1-4ubuntu5.11
