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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
