SQLite before 3.54.0 FTS5 Heap Buffer Overflow via fts5MergeRowidLists()

Impact

SQLite before 3.54.0 has a heap buffer overflow in fts5MergeRowidLists() when merging detail=none prefix doclists, allowing attackers with access to populate a detail=none FTS5 table and run a prefix MATCH query to corrupt heap memory and crash the process. The weakness is an out-of-bounds write. Attackers need to populate a table and run a query.

Original source description

SQLite before 3.54.0 built with FTS5 contains a heap buffer overflow in fts5MergeRowidLists() that undersizes the output buffer when merging detail=none prefix doclists. Attackers who can populate a detail=none FTS5 table with negative rowids and run a prefix MATCH query can write past the allocation, corrupting heap memory and crashing the process.
