The Asterisk Development Team has announced security releases for Certified
Asterisk 11.6 and Asterisk 11, 12, and 13. The available security releases are
released as versions 11.6-cert9, 11.14.2, 12.7.2, and 13.0.2.

These releases are available for immediate download at
http://downloads.asterisk.org/pub/telephony/asterisk/releases

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.

For a full list of changes in the current releases, please see the ChangeLogs:
