CVE-2020-13435

SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.

SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.

SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.

SQLite is a C library that implements an SQL database engine. A large subset of SQL92 is supported. A complete database is stored in a single disk file. The API is designed for convenience and ease of use. Applications that link against SQLite can enjoy the power and flexibility of an SQL database without the administrative hassles of supporting a separate database server.

Security Fix(es):

• sqlite: out-of-bounds access due to the use of 32-bit memory allocator interfaces (CVE-2019-5827)

• sqlite: dropping of shadow tables not restricted in defensive mode (CVE-2019-13750)

• sqlite: fts3: improve detection of corrupted records (CVE-2019-13751)

• sqlite: mishandling of certain SELECT statements with non-existent VIEW can lead to DoS (CVE-2019-19603)

• sqlite: NULL pointer dereference in sqlite3ExprCodeTarget() (CVE-2020-13435)

  • CVE-2020-13425

In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and segmentation fault because of generated column optimizations (CVE-2020-9327).

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 (CVE-2020-11655).

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).

This update for sqlite3 fixes the following issues:
