2023 Changelog

Backported in #56509: Allow backup of materialized view with dropped inner table instead of failing the backup. #56387 (Kseniia Sumarokova).
Backported in #56929: There was a potential vulnerability in previous ClickHouse versions: if a user has connected and unsuccessfully tried to authenticate with the "interserver secret" method, the server didn't terminate the connection immediately but continued to receive and ignore the leftover packets from the client. While these packets are ignored, they are still parsed, and if they use a compression method with another known vulnerability, it will lead to exploitation of it without authentication. This issue was found with ClickHouse Bug Bounty Program by https://twitter.com/malacupa. #56794 (Alexey Milovidov).

Backported in #57020: There was an attempt to have the proper listing in #44311, but the fix itself was in the wrong place, so it's still broken. See an example. #56989 (Mikhail f. Shiryaev).

Backported in #57111: Fix ON CLUSTER queries without the database being present on an initial node. Closes #55009. #56484 (Nikolay Degterinsky).
Backported in #57169: Fix crash due to buffer overflow while decompressing malformed data using Gorilla codec. This issue was found with ClickHouse Bug Bounty Program by https://twitter.com/malacupa. #57107 (Nikolay Degterinsky).
Backported in #57175: Close interserver connection for any exception that happens before the authentication. This issue was found with ClickHouse Bug Bounty Program by https://twitter.com/malacupa. #57142 (Antonio Andelic).
