POODLE - Definition from the Hotspot Shield Glossary
Not to be confused with the breed of dog, POODLE stands for Padding Oracle on Downgraded Legacy Encryption and is a form of computing exploit.
The attacker attempts to use a Man in the Middle exploit and use the Internet and Security software client’s fallback to SSL 3.0 in order to obtain data from encrypted messages. A member of the Google security team announced the POODLE vulnerability in October 2014 and it is not considered as serious as other forms of attacks such as Shellshock and Heartbleed.
There are numerous ways to defend against POODLE attacks, and Google has implemented several patches into programs like Google Chrome; Firefox and Internet Explorer have also received similar updates and Microsoft has included information on how to disable SSL 3.0 on its browsers.
