Application crash via lookaside size multiplication overflow
Published Apr 10, 2025 · Updated Aug 26, 2025
Integer overflow in SQLite 3.49.0 allows local users to crash an application through out-of-range lookaside configuration arguments. setupLookaside multiplies the caller-supplied slot size by the computed large-slot count as an int when deriving the small-slot count, so overflow corrupts the allocator layout calculation. Triggering the fault requires the ability to call sqlite3_db_config with SQLITE_DBCONFIG_LOOKASIDE from C code; SQL text and crafted database files cannot reach it, and the documented impact is an application crash.
