SQLite: integer overflow in SQLite

An integer overflow can be triggered in SQLite’s `concat_ws()` function. The resulting, truncated integer is then used to allocate a buffer. When SQLite then writes the resulting string to the buffer, it uses the original, untruncated size and thus a wild Heap Buffer overflow of size ~4GB can be triggered. This can result in arbitrary code execution.

sqlite: Denial of Service in SQLite

In SQLite 3.49.0 before 3.49.1, certain argument values to sqlite3_db_config (in the C-language API) can cause a denial of service (application crash). An sz*nBig multiplication is not cast to a 64-bit integer, and consequently some memory allocations may be incorrect.

sqlite: Integer Overflow in SQLite concat_ws Function

In SQLite 3.44.0 through 3.49.0 before 3.49.1, the concat_ws() SQL function can cause memory to be written beyond the end of a malloc-allocated buffer. If the separator argument is attacker-controlled and has a large string (e.g., 2MB or more), an integer overflow occurs in calculating the size of the result buffer, and thus malloc may not allocate enough memory.

SQLite SQLite3 make alltest sqlite3session.c sessionReadRecord heap-based overflow

A vulnerability was found in SQLite SQLite3 up to 3.43.0 and classified as critical. This issue affects the function sessionReadRecord of the file ext/session/sqlite3session.c of the component make alltest Handler. The manipulation leads to heap-based buffer overflow. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-248999.

sqlite: safe mode authorizer callback allows disallowed UDFs

SQLite through 3.40.0, when relying on --safe for execution of an untrusted CLI script, does not properly implement the azProhibitedFunctions protection mechanism, and instead allows UDF functions such as WRITEFILE.

sqlite: an array-bounds overflow if billions of bytes are used in a string argument to a C API

SQLite 1.0.12 through 3.39.x before 3.39.2 sometimes allows an array-bounds overflow if billions of bytes are used in a string argument to a C API.

A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0 via the idxGetTableInfo function when there is a crafted SQL query. NOTE: the vendor disputes the relevance of this report because a sqlite3.exe user already has full privileges (e.g., is intentionally allowed to execute commands). This report does NOT imply any problem in the SQLite library.

sqlite: denial of service via the appendvfs.c function

An issue found in SQLite SQLite3 v.3.35.4 that allows a remote attacker to cause a denial of service via the appendvfs.c function.

sqlite: potential use-after-free bug when processing a subquery with both a correlated WHERE clause and a "HAVING 0" clause and where the parent query is an aggregate

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.

sqlite: Out of bounds access during table rename

In SQLite 3.31.1, there is an out of bounds access problem through ALTER TABLE for views that have a nested FROM clause.

sqlite: Null pointer derreference in src/select.c

In SQlite 3.31.1, a potential null pointer derreference was found in the INTERSEC query processing.

sqlite: heap-based buffer overflow in multiSelectOrderBy due to mishandling of query-flattener optimization in select.c

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.

sqlite: use-after-free in resetAccumulator in select.c

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.

sqlite: NULL pointer dereference in ext/fts3/fts3_snippet.c via a crafted matchinfo() query

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

sqlite: Virtual table can be renamed into the name of one of its shadow tables

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.

sqlite: Use-after-free in fts3EvalNextRow in ext/fts3/fts3.c

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

sqlite: NULL pointer dereference in sqlite3ExprCodeTarget()

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

sqlite: integer overflow in sqlite3_str_vappendf function in printf.c

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

sqlite: use-after-free in the ALTER TABLE implementation

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: NULL pointer dereference and segmentation fault because of generated column optimizations

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