Debian DLA-1523-1 : asterisk security update

high Nessus Plugin ID 117810

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
