The release of these versions resolves the following security vulnerability:

* AST-2014-019: Remote Crash Vulnerability in WebSocket Server

  When handling a WebSocket frame the res_http_websocket module dynamically
  changes the size of the memory used to allow the provided payload to fit. If a
  payload length of zero was received the code would incorrectly attempt to
  resize to zero. This operation would succeed and end up freeing the memory but
  be treated as a failure. When the session was subsequently torn down this
  memory would get freed yet again causing a crash.

For more information about the details of this vulnerability, please read
security advisory AST-2014-019, which was released at the same time as this
announcement.
