Title:	Fedora: Security Advisory for coturn (FEDORA-2020-9eadf517de)
Summary:	The remote host is missing an update for the 'coturn'; package(s) announced via the FEDORA-2020-9eadf517de advisory.
Description:	Summary: The remote host is missing an update for the 'coturn' package(s) announced via the FEDORA-2020-9eadf517de advisory. Vulnerability Insight: 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. Affected Software/OS: 'coturn' package(s) on Fedora 31. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
