2024 Changelog

ClickHouse release v23.8.12.13-lts (bdbd0d87e5) FIXME as compared to v23.8.11.28-lts (31879d2ab4)

Bug Fix (user-visible misbehavior in an official stable release)

  • Backported in #61439: The query cache now denies access to entries when the user is re-created or assumes another role. This improves prevents attacks where 1. an user with the same name as a dropped user may access the old user's cache entries or 2. a user with a different role may access cache entries of a role with a different row policy. #58611 (Robert Schulze).
  • Backported in #61572: Fix string search with constant start position which previously could lead to memory corruption. #61547 (Antonio Andelic).
  • Backported in #61854: Fix crash in multiSearchAllPositionsCaseInsensitiveUTF8 when specifying incorrect UTF-8 sequence. Example: #61714. #61749 (pufit).
