Raccoon is a timing vulnerability in the TLS specification that affects HTTPS and other services that rely on SSL and TLS. These protocols allow everyone on the Internet to browse the web, use email, shop online, and send instant messages without third-parties being able to read the communication. Raccoon allows attackers under certain conditions to break the encryption and read sensitive communications. The vulnerability is really hard to exploit and relies on very precise timing measurements and on a specific server configuration to be exploitable.
