"The version of Junos OS installed on the remote host is affected by multiple vulnerabilities as referenced in the
JSA69705 advisory.

  - ** DISPUTED ** 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.
    (CVE-2021-36690)

  - 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. (CVE-2021-20227)

  - 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)

  - 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)

  - 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 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)

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

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

  - 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)

  - 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)

  - 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. (CVE-2020-11656)

  - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
