A flaw was found in SQLite's SELECT query functionality (src/select.c). This flaw allows an attacker who is capable of running SQL queries locally on the SQLite database to cause a denial of service or possible code execution by triggering a use-after-free. The highest threat from this vulnerability is to system availability.

CVE-2020-13871High· 7.5SQLite 3.32.2 has a use-after-free in resetAccumulator in select.c because the parse tree rewrite for window functions is too late.
CVE-2020-11656Critical· 9.8In SQLite through 3.31.1, the ALTER TABLE implementation has a use-after-free, as demonstrated by an ORDER BY clause that belongs to a compound SELECT statement.
CVE-2020-15358Medium· 5.5In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.

CVE-2020-13434Medium· 5.5SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.
CVE-2020-11655High· 7.5SQLite through 3.31.1 allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query because the AggInfo object's initialization is mishandled.
