Sean Bright discovered that Asterisk, a PBX and telephony toolkit, contained a stack overflow vulnerability in the res_http_websocket.so module that allowed remote attackers to crash Asterisk via specially crafted HTTP requests to upgrade the connection to a websocket.

For Debian 8 Jessie, this problem has been fixed in version 1:11.13.1~dfsg-2+deb8u6.

We recommend that you upgrade your asterisk packages.
