Integer wraparound in PostgreSQL fuzzystrmatch allows a user to direct writes to a huge range of addresses, executing arbitrary code as the operating system user running the database, via extreme inputs to SQL function levenshtein() or levenshtein_less_equal(). Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
