-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-dda1360c18 2026-06-24 01:28:48.584565+00:00 -------------------------------------------------------------------------------- Name : coturn Product : Fedora 44 Version : 4.13.1 Release : 1.fc44 URL : https://github.com/coturn/coturn/ Summary : TURN/STUN & ICE Server Description : 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. -------------------------------------------------------------------------------- Update Information: Coturn 4.13.1 What's in this release Security fixes What's Changed Null-terminate server_name in stun_is_challenge_response_str Canonicalize all IPv4-in-IPv6 encodings before peer-IP checks Auto-deny coturn's own database backend endpoints as relay peers Deny link-local / ULA / site-local relay peers by default Coturn 4.13.0 What's in this release More performance improvements for --udp-recvmmsg and --multiplex-peer. If your system does not rely on TURN unique ports give multiplexing a try - it has capacity to dramatically increase performance. Security fixes What's Changed Wrap atomic everywhere Fix sendmmsg stride bug in multiplex-peer UDP batch flush Reap TURN permissions/channels via a per-thread sweep instead of per-object timers Add --udp-sendmmsg-log to observe egress sendmmsg/UDP-GSO batching Expose recvmmsg/sendmmsg UDP batch sizes as Prometheus metrics Restrict recvmmsg fast path to shared fan-in sockets (make --udp-recvmmsg useful standalone) Enable --udp-recvmmsg by default on Linux Security hardening: port parsing, admin brute-force throttle, credential log redaction, constant-time compare, OAuth bounds checks, permission cap Add continuous latency mode to stunclient Fix test_redis_format link failure Fix configure MANPREFIX typo Fix missing sqlite3 dependendcy Fix UDP receive buffer ownership -------------------------------------------------------------------------------- ChangeLog: * Tue Jun 16 2026 Robert Scheck <robert@fedoraproject.org> - 4.13.1-1 - Upgrade to 4.13.1 (#2488712 #c1) * Sun Jun 14 2026 Robert Scheck <robert@fedoraproject.org> - 4.13.0-1 - Upgrade to 4.13.0 (#2488712) * Fri Jun 12 2026 Yaakov Selkowitz <yselkowi@redhat.com> - 4.12.0-3 - Rebuilt for openssl 4.0 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2490558 - CVE-2026-43915 coturn: Coturn: Cross-Site Scripting (XSS) via crafted username in TURN allocation https://bugzilla.redhat.com/show_bug.cgi?id=2490558 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
