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.
