Debian Security Advisory DSA-4829-1 [email protected]

Package : coturn
CVE ID : CVE-2020-26262
A flaw was discovered in coturn, a TURN and STUN server for VoIP. By
default coturn does not allow peers on the loopback addresses
(127.x.x.x and ::1). A remote attacker can bypass the protection via a
specially crafted request using a peer address of '0.0.0.0' and trick
coturn in relaying to the loopback interface. If listening on IPv6 the
loopback interface can also be reached by using either [::1] or [::] as
the address.
For the stable distribution (buster), this problem has been fixed in
version 4.5.1.1-1.1+deb10u2.
We recommend that you upgrade your coturn packages.
For the detailed security status of coturn please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/coturn
