vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - sqlite: incorrect sqlite3WindowRewrite() error handling leads to mishandling certain parser-tree rewriting
    (CVE-2019-19924)

  - sqlite: Use-after-free in fts3EvalNextRow in ext/fts3/fts3.c (CVE-2020-13630)

  - os_unix.c in SQLite before 3.13.0 improperly implements the temporary directory search algorithm, which
    might allow local users to obtain sensitive information, cause a denial of service (application crash), or
    have unspecified other impact by leveraging use of the current working directory for temporary files.
    (CVE-2016-6153)

  - The dump_callback function in SQLite 3.20.0 allows remote attackers to cause a denial of service
    (EXC_BAD_ACCESS and application crash) via a crafted file. (CVE-2017-13685)

  - SQLite 3.20.1 has a NULL pointer dereference in tableColumnList in shell.c because it fails to consider
    certain cases where `sqlite3_step(pStmt)==SQLITE_ROW` is false and a data structure is never initialized.
    (CVE-2017-15286)

  - sqlite3Select in select.c in SQLite 3.30.1 allows a crash if a sub-select uses both DISTINCT and window
    functions, and also has certain ORDER BY usage. (CVE-2019-19244)

  - SQLite 3.30.1 mishandles certain SELECT statements with a nonexistent VIEW, leading to an application
    crash. (CVE-2019-19603)

  - alter.c in SQLite through 3.30.1 allows attackers to trigger infinite recursion via certain types of self-
    referential views in conjunction with ALTER TABLE statements. (CVE-2019-19645)

  - exprListAppendList in window.c in SQLite 3.30.1 allows attackers to trigger an invalid pointer dereference
    because constant integer values in ORDER BY clauses of window definitions are mishandled. (CVE-2019-19880)

  - selectExpander in select.c in SQLite 3.30.1 proceeds with WITH stack unwinding even after a parsing error.
    (CVE-2019-20218)

  - 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)

  - 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)

  - 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package
is installed.");
