Debian DLA-2271-1 : coturn security update

high Nessus Plugin ID 138064

Language:

Synopsis

The remote Debian host is missing a security update.

Description

In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client (an attacker) could use their connection to intelligently query coturn to get interesting bytes in the padding bytes from the connection of another client.

For Debian 8 'Jessie', this problem has been fixed in version 4.2.1.2-1+deb8u2.

We recommend that you upgrade your coturn 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 coturn package.
