Heap-based buffer overflow in PostgreSQL tsvector_delete() allows a database user to execute arbitrary code as the operating system user running the database, via a tsvector whose lexeme data uses a nonstandard but valid ordering that requires additional alignment padding in the result. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
