* SECURITY UPDATE: prepared statement use-after-free in CREATE INDEX/ALTER TABLE - debian/patches/CVE-2024-21193.patch: When an expression is used in the index clause of a CREATE TABLE, CREATE INDEX, or ALTER TABLE ADD INDEX statement within a prepared statement, subsequent executions encounter an error due to use-after-free of MEM_ROOT pointers. The fix forces reprepare/reparse of the affected prepared statements prior to second and subsequent executions. - CVE-2024-21193 * SECURITY UPDATE: crash when repreparing prepared statements repeatedly - debian/patches/CVE-2024-21204.patch: Adds a null check for the reprepare observer in stored-routine execution: when ER_NEED_REPREPARE fires but no observer is set, the function now returns an error instead of hitting an assertion that crashes the server. - CVE-2024-21204
