[SECURITY] [DLA 2271-1] coturn security update



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

Package        : coturn
Version        : 4.2.1.2-1+deb8u2
CVE ID         : CVE-2020-4067


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.
