SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.

In 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.

SQLite 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.

In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and segmentation fault because of generated column optimizations.

ext/misc/zipfile.c in SQLite 3.30.1 mishandles certain uses of INSERT INTO in situations involving embedded '\0' characters in filenames, leading to a memory-management error that can be detected by (for example) valgrind.

selectExpander in select.c in SQLite 3.30.1 proceeds with WITH stack unwinding even after a parsing error.

zipfileUpdate in ext/misc/zipfile.c in SQLite 3.30.1 mishandles a NULL pathname during an update of a ZIP archive.

SQLite 3.30.1 mishandles certain parser-tree rewriting, related to expr.c, vdbeaux.c, and window.c. This is caused by incorrect sqlite3WindowRewrite() error handling.

flattenSubquery in select.c in SQLite 3.30.1 mishandles certain uses of SELECT DISTINCT involving a LEFT JOIN in which the right-hand side is a view. This can cause a NULL pointer dereference (or incorrect results).

multiSelect in select.c in SQLite 3.30.1 mishandles certain errors during parsing, as demonstrated by errors from sqlite3WindowRewrite() calls. NOTE: this vulnerability exists because of an incomplete fix for CVE-2019-19880.
