    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:
