SQLite before 3.54.0 Heap Buffer Overflow via FTS5 fts5DoSecureDelete()

Impact

SQLite before 3.54.0 has a heap buffer overflow via FTS5 fts5DoSecureDelete(), allowing attackers to corrupt heap memory and crash the application with a crafted database file. Attackers need access to supply a corrupted FTS5 index. The weakness is an out-of-bounds write.

Original source description

SQLite before 3.54.0 built with FTS5 contains a heap buffer overflow in fts5DoSecureDelete() that allows attackers to write past the leaf page buffer via crafted footer key offsets. Attackers can supply a database file with a corrupted FTS5 index that, when deleted from with secure-delete enabled, corrupts heap memory and crashes the application.
