openSUSE-SU-2026:21184-1

This update for coturn fixes the following issues:

Changes in coturn:

• Update to version 4.14.0 New

  • No more dependency on prometheus-client-c
  • HTTPS support for prometheus client (optional)
  • TLS support for redis - now compatible with managed redis (optional).
  • Rate limiting "401 Unauthorized" responses - reduces reflection attacks off the coturn server. This is an experimental feature - not fully tested on production scale deployment and massive DDoS attacks. New prometheus counters should help shed some light on real life behavior and performance. The feature is off by default. What's Changed
  • validate hmackey length in sqlite_get_user_key before hex decode.
  • Add out-of-tree patch to restore deprecated OpenSSL 1.1.1.
  • Add optional TLS transport for Redis connections.
  • Fix relay threads override.
  • Flush prometheus hot-path counters once per second to kill lock contention.
  • fix signed-char index out-of-bounds read in base64_decode.
  • Build Prometheus exporter from vendored local sources.
  • Prom https.
  • Fix realm quota data race and warnings.
  • Add per-source rate-limiting of UDP 401 Unauthorized responses

• Update to version 4.13.1
