    CVE-2020-26262

    Summary: Updated coturn package fixes a security vulnerability

    Details: When sending a CONNECT request with the XOR-PEER-ADDRESS value of 0.0.0.0, a malicious user would be able to relay packets to the loopback interface. Additionally, when coturn is listening on IPv6, which is default, the loopback interface can also be reached by making use of either [::1] or [::] as the peer address (CVE-2020-26262). If updating is not possible, the setting --denied-peer-ip=0.0.0.0 can mitigate this issue. The coturn package has been patched to fix this issue.
