vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption)
attack to decrypt SSL sessions and access the plaintext of encrypted
connections.

IBM recommends that you review your entire environment to identify areas that
enable the SSLv3 protocol and take appropriate mitigation and remediation
actions. The most immediate mitigation action that can be taken is disabling
SSLv3. You should verify disabling SSLv3 does not cause any compatibility
issues.
ATTENTION: Changes on both client and host are required, and these must happen
simultaneously.
