An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2020:4442 advisory.

  - An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0.
    A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote     code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
    (CVE-2019-5018)

  - In SQLite through 3.29.0, whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application     because of missing validation of a sqlite_stat1 sz field, aka a severe division by zero in the query     planner. (CVE-2019-16168)

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

  - Out of bounds read in SQLite in Google Chrome prior to 80.0.3987.87 allowed a remote attacker to obtain     potentially sensitive information from process memory via a crafted HTML page. (CVE-2020-6405)

  - 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)

  - 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)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4442 advisory.

    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: Use-after-free in window function leading to remote code execution (CVE-2019-5018)

    * sqlite: Division by zero in whereLoopAddBtreeIndex in sqlite3.c (CVE-2019-16168)

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

    * sqlite: Out-of-bounds read in SELECT with ON/USING clause (CVE-2020-6405)

    * sqlite: NULL pointer dereference and segmentation fault because of generated column optimizations     (CVE-2020-9327)

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

    * sqlite: Virtual table can be renamed into the name of one of its shadow tables (CVE-2020-13631)

    * sqlite: NULL pointer dereference in ext/fts3/fts3_snippet.c via a crafted matchinfo() query     (CVE-2020-13632)
