"A man-in-the-middle (MitM) information disclosure vulnerability,
known as POODLE, exists due to the way SSL 3.0 handles padding bytes
when decrypting messages encrypted using block ciphers in cipher block
chaining (CBC) mode. A MitM attacker can decrypt a selected byte of a
cipher text in as few as 256 tries if they are able to force a victim
application to repeatedly send the same data over newly created SSL
3.0 connections.");
