that is prior to version 2.2.5. It is, therefore, affected by an
information disclosure vulnerability.

An error exists related to the way SSL 3.0 handles padding bytes when
decrypting messages encrypted using block ciphers in cipher block
chaining (CBC) mode. A man-in-the-middle 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. This is also known as the 'POODLE'
issue.");
