Description
A flaw was found in SQLite. A heap-based buffer overflow exists in the Full-Text Search 5 (FTS5) extension during the merging of prefix document lists. An attacker capable of inserting negative row identifiers into a configured table and executing a prefix search query can cause data to be written beyond allocated memory. This issue can lead to memory corruption, resulting in application crashes, a Denial of Service (DoS), or potentially arbitrary code execution.
