Unfortunately, a lot of services and servers depend on SSL, not just HTTPS sites.
Like: mail servers, SSH, and other business applications use custom port depend on SSL, and they all need to be updates to stop supporting SSLv3.
All systems and applications utilizing the Secure Socket Layer (SSL) 3.0 with cipher-block chaining (CBC) mode ciphers may be vulnerable. However, the POODLE (Padding Oracle on Downgraded Legacy Encryption) attack demonstrates this vulnerability using web browsers and web servers, which is one of the most likely exploitation scenarios.
