  - An information disclosure vulnerability, known as BEAST,     exists in the SSL 3.0 and TLS 1.0 protocols due to a     flaw in the way the initialization vector (IV) is     selected when operating in cipher-block chaining (CBC)     modes. A man-in-the-middle attacker can exploit this     to obtain plaintext HTTP header data, by using a     blockwise chosen-boundary attack (BCBA) on an HTTPS     session, in conjunction with JavaScript code that uses     the HTML5 WebSocket API, the Java URLConnection API,     or the Silverlight WebClient API.
