What's New in v19.2.0-rc.3

This version of CockroachDB is no longer supported. For more details, see the Release Support Policy.

November 4, 2019


A denial-of-service (DoS) vulnerability is present in CockroachDB v19.2.0 - v19.2.11 due to a bug in protobuf. This is resolved in CockroachDB v19.2.12 and later releases. When upgrading is not an option, users should audit their network configuration to verify that the CockroachDB HTTP port is not available to untrusted clients. We recommend blocking the HTTP port behind a firewall.

For more information, including other affected versions, see Technical Advisory 58932.
