Description Pedro Sampaio 2018-09-24 21:11:28 UTC 
There is a stack overflow vulnerability in the res_http_websocket.so module of Asterisk that allows an attacker to crash Asterisk via a specially crafted HTTP request to upgrade the connection to a websocket. The attacker’s request causes Asterisk to run out of stack space and crash.
