consul v1.9.9 Release Notes

Release Date: 2021-08-27 // over 2 years ago

  • KNOWN ISSUES:

    • 🚀 tls: The fix for CVE-2021-37219 introduced an issue that could prevent TLS certificate validation when intermediate CA certificates used to sign server certificates are transmitted in the TLS session but are not present in all Consul server's configured CA certificates. This has the effect of preventing Raft RPCs between the affected servers. As a work around until the next patch releases, ensure that all intermediate CA certificates are present in all Consul server configurations prior to using certificates that they have signed.

    🔒 SECURITY:

    👌 IMPROVEMENTS:

    • areas: (Enterprise only) Add 15s timeout to opening streams over pooled connections.
    • areas: (Enterprise only) Apply backpressure to area gossip packet ingestion when more than 512 packets are waiting to be ingested.
    • areas: (Enterprise only) Make implementation of WriteToAddress non-blocking to avoid slowing down memberlist's packetListen routine.
