SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c (CVE-2020-13434).

SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c (CVE-2020-13435).

ext/fts3/fts3.c in SQLite before 3.32.0 has a use-after-free in fts3EvalNextRow, related to the snippet feature (CVE-2020-13630).

SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c (CVE-2020-13631).

ext/fts3/fts3_snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo() query (CVE-2020-13632).

SQLite 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-2020-13871).

In 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-2020-15358).
