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.
