Description (partial)

Forced downgrade of connections to SSL 3.0 even if both server and client sides of the connection
support higher protocols.

The problem comes when the secure connection is downgraded to use SSL 3.0 when higher level TLS communication failed by an attacker in the middle of a connection ie Whenever SSL handshake is negotiated with version 3.0. then the attacker may be able to force the browser to do exactly what it's designed to do. The problem is limited to SSLv3 only.
