Fedora 32 FEDORA-2021-32d0068851 Critical: coturn DoS Security Fixes

The Coturn TURN Server is a VoIP media traffic NAT traversal server and gateway.

It can be used as a general-purpose network traffic TURN server/gateway, too.

This implementation also includes some extra features. Supported RFCs:

TURN specs:

- RFC 5766 - base TURN specs

- RFC 6062 - TCP relaying TURN extension

- RFC 6156 - IPv6 extension for TURN

- Experimental DTLS support as client protocol.

STUN specs:

- RFC 3489 - "classic" STUN

- RFC 5389 - base "new" STUN specs

- RFC 5769 - test vectors for STUN protocol testing

- RFC 5780 - NAT behavior discovery support

The implementation fully supports the following client-to-TURN-server protocols:

- UDP (per RFC 5766)

- TCP (per RFC 5766 and RFC 6062)

- TLS (per RFC 5766 and RFC 6062); TLS1.0/TLS1.1/TLS1.2

- DTLS (experimental non-standard feature)

Supported relay protocols:

- UDP (per RFC 5766)

- TCP (per RFC 6062)

Supported user databases (for user repository, with passwords or keys, if

authentication is required):

- SQLite

- MySQL

- PostgreSQL

- Redis

Redis can also be used for status and statistics storage and notification.

Supported TURN authentication mechanisms:

- long-term

- TURN REST API (a modification of the long-term mechanism, for time-limited

secret-based authentication, for WebRTC applications)

The load balancing can be implemented with the following tools (either one or a

combination of them):

- network load-balancer server

- DNS-based load balancing

- built-in ALTERNATE-SERVER mechanism.

memory - Add prometheus metrics - Delete trailing whitespace in example

configuration files - Add architecture ppc64le to travis build - Fix

misleading option in doc (prometheus) - Allow RFC6062 TCP relay data to look

like TLS - Add support for proxy protocol V1 - Print full date and time in

logs - Add new options: "new-log-timestamp" and "new-log-timestamp-format" -Do not use FIPS and remove hardcode `OPENSSL_VERSION_NUMBER` with LibreSSL -Add ACME redirect url - Support of `--acme-redirect ` - Fix acme

security, redundancy, consistency - Disable binding request logging to avoid

DoS attacks (Breaking change!) - Add new `--log-binding` option to enable

binding request logging - Fix stale-nonce documentation - Version number is

changed to semver 2.0 - pkg-config, and various cleanups in configure file -Add systemd notification for better systemd integration - Fix: Null pointer

dereference on tcp_client_input_handler_rfc6062data function - Fix: use-after-free vulnerability on write_to_peerchannel function - Fix: use-after-free

vulnerability on write_client_connection function - Little refactoring

prometheus - Fix c++ support - Simplify - Remove session

id/allocation labels - Remove per session metrics - Fix CVE-2020-26262

- Fix ipv6 ::1 loopback check - Not allow allocate peer address 0.0.0.0/8
